I have a ready design of a power supply circuit and it is 20V,3A. But I need it to be done for 12v,5A. I have a design of transformer too which is for 12v,5A.
My switching frequency is 29KHz and have designed a transformer with the same switching frequency.
Please let me know, do I have to change (...)

I had using the 24V 15A SMPS now, but its getting problem with my application. So i thought to ready with own power supply design. I having the confusion to choosing the transformers and whats range have to select. My output wants dual 24V output with 15A each and 12v 5A. This was my output requirements. Could anybody suggest the idea (...)

Hi, i need a power supply circuit. I will use it for;
1- Obtain 5V 1A for microcontroller circuit
2- Obtain 12v 1A for backlight
3- Obtain 24-29V 5A for drive dc motors
4- Obtain 100mA constant charge circuit for charge 24V battery
My circuit must work with AC (...)

I need to provide a high side load switch for a power supply coming from a battery...
i.e. 12v Battery > High side switch> DC voltage at Load rated at 5A
The load switch should be able to detect open/short, over load conditions.
My question is if I?m using an N channel device then I should use some sort of charge pump driver that (...)

I think you need to buy the transformer (with 12vAC output), bridge rectifier, 12v regulator (7812 with can housing is good choice, it supports upto 5A current).

for laptop a small attachment is available with inbuilt fan powered from usb port, there is no need of additional power supply,
if you want to your own if you want it to carry better go for smps type and there is no need of 5A supply, maxim 1A will do for 3 fans( it takes 12v around .15A for one)

I need to build a power supply to drive a 150W Cermax xenon lamp. I'm thinking about modding a PC power supply by adding an ignitor circuit.
This kind of lamps requires a 28Kv pulse during 100ns for turn them on, and its consumption in steady state is 12,5A @ 12v approximately. (...)
