Re: A little power circuit explanation please

The regulator needs about 2.5 to 3 volts head room. The circuit is what is often called a boost circuit. If my calculations are right, it should produce about 15.5 to 16V on C10. This gives the regulator enough over voltage to work as a regulator. If the supply you have is not regulated it

Here is the situation. The + 5V 12A that collapses comes out from pins 10-14 / 36-40, the other + 5V 12A (pins 15-22 / 36-40) never goes down. All that I surrounded in green on that image (1950×2361, zoomable) are the components that I tested on the power supply G2, A3 motherboard,
