suggestion on large power rated MOSFET

NDS352AN and NDS352AP have been used for the switch as shown in the circuit. It works well for a bus-powered device. But for self-powered devices, it is not on/OFF the unit switch.
To condition, 5v is out to OFF also it gives 4.5V, so the power is always on.

Any suggestions?

Thank you

Only you can answer, you should know how much current will pass through it, how much power loss will be based on Rds_on.  If your simulation just, whatever it is will be 'ok', but you only know what your app is and consider what your needs are... I want to run my max at 50% of the capacity of the apparatus... because I can... but usually avoid anything over 85% of the maximum values... Good luck

  • Satellite A60 turns off when the only power is connected

    Hello

    Recently my original adapter has stopped working and I bought a new one. However, the problem with this new is that when it works perfectly until you hear the windows that open sounds and then she just turns off. But when I plug the AC with the battery connected to the laptop, it works fine. It's just that it will not correctly work with just the AC is plugged.

    HEY Fan Wai,

    It seems that your new adapter cannot supply enough current to power your laptop when it is under load. I suggest you check the rated power of the new adapter agaoinst those of the original.

    Kind regards

  • Pavilion M7567C power is compatible with a 1220 N?

    My Pavilion n 1220 has absolutely no power.  Wonder if I can pass the power supply of my Pavilion M7567C, also not functioning, to the a1220n.  Any help will be appreciated.

    Absolutely, you can replace the power supply of your M7567C to your a1220n. Sure just that the power rating (watts) is the same or higher to be replace. I assume that both are 250 Watt PSU, but even once, make sure that you do not replace a larger unit of watt with a smaller unit.

  • 29W power supply will work for iPad 9.7 Pro

    My iPad Pro 9.7 inches provided with a power of 10 watts. It takes about six hours is responsible for the depletion of the layer to be 100% responsible. I would like to be able to do it faster. I noticed that the iPad Pro with a larger screen has a 29 Watt power supply available in the Apple Store. I bought this with the cable Apple to convert USB type C USB 2, which I am connected to my Flash a USB cable.  When I try on my Pro 9.7 inch iPad it charges no faster than six hours. Anyone who has tried using a larger power and they have managed to improve the loading time?

    The smaller iPad Pro does not have lightning speed USB - C compliant connector which has the bigger iPad Pro, so the special USB - C cable and 29W power supply wiil lightning does not work with the smaller iPad Pro to load more quickly.

    Return these back to Apple for a full refund.

  • HP ENVY PHOENIX CTO 810-135QE - 600 watts power supply Question

    In the near future, I would like to upgrade the video card in my desktop HP ENVY PHOENIX CTO 135QE-810 GT 640 default to something a little more powerful and I was wondering if there is any details about the default 600 watts power that will help me in my decision to the next video card.

    I know that some video cards require a number of amps on the 12 volt rail and all the information that I have found previously on the power of 600 watts power supply in the computer is not in that kind of detail.

    What I read, the power is a Petrus 600W e-star 5.0 Bronze, HP Part number 633186-002.

    Any additional details and details on this power to help me determine the next video card would be useful.

    On a side note the video card, I'm currently doing is one of the next Nvidia GTX 750 TI models, thoughts and recommendations on this specific map?

    Thank you

    Hello

    Your PC has UEFI bios, so most video cards should work.  Some video cards will work in UEFI mode and others in legacy mode, that your PC is able to run.

    When the manufacturer of the video card and/or AMD or NVIDIA specify a minimum power supply size then it is best to stick to this recommendation.  Not all power supplies are built to the same standards of quality.  In addition the internal components, temperature, charges unknown and time that the PC will be placed under the maximum load are taken into account at the recommendation of minimum power supply is indicated.

    I have not seen a power of 500 watts with 12v rating of 18A, but this does not mean that there is not. And if that's the case, then the total power rating is suspect. A video card that requires an external auxiliary power connector will also draw power from the PCI-E slot.

    Are there cases where the minimum size of the power supply is insufficient? Yes, those who might be extreme but someone can have connected to power different connectors either to avoid buying a new power supply or maybe around just the food manufacturer minimum power rating. Some may do it thinking 'I'm going on fox the Fox ". It can work, but maybe the questions later start occurred.  I prefer to get the job done right the first time. You don't need a power supply to perhaps of overload and short circuit then internally causing spikes to the components in the PC.

    Since we do not know what may have suggested to Jim, power cycle your router and the printer and force restart the iPad. Unplug the router and the printer power for 30 seconds. Plug in the router first and let it restart. And then reconnect the printer power supply. Then force restart the iPad. To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.

    http://h20565.www2.HP.com/portal/site/hpsc/template.page/public/KB/docDisplay/?sp4ts.Oid=5187022&... Also, where can I find this card on the motherboard? I don't see or I could have missed it.

    3. Moreover, if I were to upgrade the processor, which will be I need and how to replace the CPU?

    4. What is the recommended CPU to run at the same power original power supplied with my computer when I first bought it?

    5 How can. one last thing, I upgrade and replace the graphics card if this computer comes with the integrated graphics card of base/stock/default on this computer?

    I'm not very tech savy, or a computer programmer/Assistant. Help, please. Thank you!

    This is the original factory specifications for your desktop HP Pavilion p7-1254. Here are the specifications of the card mother AAHD2-HY (Holly) installed on your computer.

    (1) wireless card and its location;

     

    (2) CPU upgrades;

    Image AMD A8-3850 (Liano) 100W
    Image AMD A8-3800 (Liano) 65W
    Image AMD A6-3650 (Liano) 100W

    No need to replace the power supply to allow an upgrade of the CPU.

    (3) graph and power upgrade;

    This computer using integrated graphics supported by the motherboard and APU. Installation of a discrete graphics card will automatically disable the integrated graphics card. This model supports a v2.0, v2.1 or card discrete graphics PCIe x 16 v3.0 Specification v2.0. For all but the most basic graphics cards, you will need to supply. I suggest using the power supply Corsair CX500, CX600, CX500M, and CX600M.

    Please see HP - addition / replacement of material and select the appropriate necessary topic for instructions.

  • Pavilion 550-150qe: graphics and power for 550-150qe

    Hello

    My nephew wants to upgrade the graphics card in his 5501150qe and will probably need to upgrade to the power supply, too.   It's a small suitcase and the first card he bought was too big (it did not before).  It has now become a Msi GeForce gt 740 live x 12 4 GB. Can anyone suggest a compatible power and there will be cooling problems?

    Thank you-

    This is a power supply unit (PSU) that must work for him.  The first thing to do is to measure the existing PSU and to compare measures of the link.  This ensures that the other is insert in space.

  • Pavilion 500-217: 500-217 HP. new power supply

    Has anyone upgraded the power on this machine? The new GPU I want says it requires 400w and this one has only 300w.  Also, if I ignored that, this device seems not having all the extra power connectors that I see in any case.

    Does anyone have a suggestion of a power supply meets these requirements?

    Thanks, I was really considering this one. Reassessed to my needs and I'm going with the CX500. Appreciate the comments.

  • Power requirements of proDock II

    I have a question about the ProDock II (model NP. DCK11.00Q) for use with a PC laptop TravelMate P645. ProDock specifications state that it requires a 90 Watt power supply to work properly. The power adapter supplied with the P645 is 65 Watts. Looking for all the description and pictures I could find of the ProDock, none show or even suggest a like power adapter included with the dock. Furthermore, Acer does not apparently a power separate from 90 watts for this dock - sell adapters of only 65 watts as the one I currently have. So if I buy the ProDock II, will it start hunting around for some non - OEM 90 Watt power supply with a specific Canon connector?

    Thanks to you all.  I am pleased to announce that the ProDock II includes the 90 Watt power supply as I had hoped, and as suggested by the responses in this thread.  The box and seal had dedicated compartments for each component, including the docking station, processing power adapter to 2 parts and a manual.

    The adapter closely resembles the one supplied with the TravelMate (both are made by Chicony), although the segment that connects the pier has a thicker cord and transformer feels heavier.  Food indeed indicates a 90 watts of power, so probably wouldn't be confused with the TravelMate adapter when plug it directly into the laptop could damage it.  On the other hand, the Canon plugs can be slightly different and effectively that refuse to perform.  I don't check this detail, however, prior to this announcement.

    I promised to report to the thread about this, where this post.  Thanks again to all who have responded.  It should be noted that the dock is set up and works well.  It certainly seems a worthwhile investment as a quick Coupler for those travelling companions.  I can devote peripheral House including the speakers usb, keyboard and mouse, and best of all - I have to mess with connection and disconnection, and packing and unpacking of this danged power adapter more

  • Iconia W4-820 will not charge with the power adapter USB Std

    Bought my W4 Iconia four weeks ago, a demonstration model, the last of them. It was packed in the box with a micro USB x adapter USB OTG cable and a power adapter. Back at home I discovered that the power adapter has been to Asus, possibly mixed in the shop. The prospective buyer of the Asus Tablet demo likely will get the Acer adapter. Adapter Asus with micro USB male connector works fine; specs are 5.2V - 1.35 amps; seems to be a STD USB adapter. The Asus adapter has a connector to USB female port to connect to a USB x microphone cable to USB adapter (with cable power adapter came in the box). Bought a 2nd power with USB 2 socket adapter to connect my W4 Iconia and my Garmin Zumo390 browser to an adapter. Specs are 5V - 3.5 amps.
    The Zumo works very well with the new card, but does not work my W4. Charge light stays off. USB ports switched to he Zumo and the Iconia W4, but same result. Zumo fresh, but W4 not. Borrowed another power adapter USB, 5V - 2 mines anti-personnel and new Zumo accusations, but the W4 still does not work. Also tried different USB adapter cables, but the same thing; Zumo invoice, W4 does not work.
    How is that possible? I can't tell the difference of 0.2 V between the Asus adapter and a USB adaptor STD would make the difference. But maybe I'm wrong. Wanted for adapters for the W4 Iconia and found several, but all the 5V as expected.
    Can anyone help.
    Will go to the shop again next week, but if I need an adapter V 5.2 I should order with Acer. 5.2 V adapters do exist not (readibly).

    Resolved issues. A dark and humid Sunday afternoon back to the store with the Tablet and all the bells and whistles. Changed the card Asus for the original Acer 5V - 2Amps (10W). Took the time to find the Acer adapter in the store. Demonstrated the adapter 2nd with 2 output USB ports and it wouldn't work with the Tablet W4. Tried another and found to be ok. 2 USB ports have a different power, a port for a smartphone and the other port is one tablet. Total power rating of the adapter is 17.5W (5V - 3.5Amps); some 2.5 and 1Amps. A happy man is back home again.
