General Description
APW1680 designed minimize external components personal-computer switching power supply systems. provides protection circuits, power good indicator, fault protection output control. (over voltage protection) monitors 3.3V, detects terminal). (under voltage protection) monitors 3.3V When condition detected, (power good output) latched high. PSON from high resets protection latch. Power good feature monitors PGI, 3.3V under voltages, issues power good signal when they ready.
