5V Switching Power Supply

5V 10A Switching Regulator circuit Using L4970A

Friends that seek 5V 10A power supply circuit small-sized and build easy. I begs for to advise this circuit. It is 10A switching regulator by use IC L4970A. Then build easy as an example integrated readymade circuit. Important point be power supply input must have 10A current sizes then can give power get enough.


The detail is other of the circuit almost must not fine to decorate anything. If friends take an interest try seek buy the integrated circuit and other equipment. come to try build immediately yes.

Switching power supply Regulator 0-40V 4A by L296

Specificaly for the chip that is used in this circuit data are like this: Oscilator runs at freq 200kHz, output noise is below 1% (worst case), max current is 4A at 20V. Voltage can be regulated from 0,0 V (true zero), to 40 V. Voltage and current limit, can be adjusted. You should take special care when purchasing choke. Its ferrite material should be build for frequencies up to 300kHz. Input to theregulator can be DC or AC voltage – becouse the input is rectifier bridge.
