Easy 5V 10A switching regulator by 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.

12VDC to 37V DC converter by SG3524

12VDC to 37V DC converter by SG3524
Hello there!! How are you doing?
When my friend of I wants DC to DC converter circuit +37V GND -37V sizes use an automobile s have Voltage 12VDC. By he takes this circuit goes to Power Supply with , Mosfet Power Amplifier 100W RMS. A hand sees 12VDC to 37V DC converter Circuit this. Will use prominent equipment interesting be IC SG3524 (Regulating Pulse-Width Modulators) Then be usable easy and convenient. Besides still power mosfet number BUZ11 6 amounts are perform drive a pot modifies the Secretariat of the Senate runs away to give electric tall many power. The detail is other see in circuit picture sir. Hope you guys had a great weekend.

Autoformer Switch-Mode Power Supply

This is a small 2*25 (actually, 2*50) WPC amplifier with 3-order crossover stage (configurable as LP or HP). Of particular interest is the unconventional autoformer PS arrangement. Since the power FET’s drains are not tied to ground anymore, it needs another transformer to drive gates. Gate driver is TL494 + MPSW56 followers, powered by REMOTE line.

The autoformer is small (25mm), windings are bifillar, single-strand 1.2mm wires. Both idle and full-load signal at secondaries is perfectly rectangular. 1:2 stepup results in 24V DC output (idle, unregulated). Idle draw is 1A @12V DC.
