Description

The APW1680 is designed to minimize the external components of personal-computer switching power supply systems. It provides protection circuits, power good indicator, fault protection output FPO and control.

OVP (over voltage protection) monitors 3.3V, 5 V, and 12 V (12 V OV detects via V CC terminal). UVP (under voltage protection) monitors 3.3V and 5V. When an OV or UV condition is detected, the PGO (power good output) is set to low and FPOis latched to high. PSON from low to high resets the protection latch.

Power good feature monitors PGI, 3.3V and 5V under voltages, and issues a power good signal when they are ready.
