ABSTRACT:
In a post regulation control circuit mainly used in a switching power supply with several sets of outputs, the circuit adopts leading edge synchronization and conduction time regulation for the control, and a leading edge of the waveform of an input voltage of a detected secondary inductor generates a sync signal to reset a ramp generator to produce a stable continuous ramp signal, and compares with a feedback voltage to generate a power conduction signal corresponding to a stable output voltage. After the power conduction signal is cut off, a flywheel conduction signal in an inverted phase is produced. The two signals separately have an output terminal for driving two power switches of power conduction and flywheel conduction. The circuit applicable for various AC or DC step-down regulators gives a stable regulation control for the switching power supply with several alternating outputs.
