MOS power IC full range The +3.3V power supply of the popular ATX power supply. +3.3V power supply by pulse The 5V winding of the output transformer T1 is stepped down by the coils L5 and L6, rectified by the common cathode Schottky rectifier block D23, and then filtered by L1 and C28. The voltage drop of L5 and L6 is related to the current passing through it. The current has a small voltage drop and a high output voltage. The voltage at no load can reach 9.5V. When the current is large, the...
