from 4 V to 15 V
The APW1680 is designed to minimize the exter-
nal components of personal-computer switching
power supply systems. It provides protection
circuits, power good indicator, fault protection out-
put 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 FPO is latched
to high. PSON from low to high resets the protec-
tion latch.
Power good feature monitors PGI, 3.3V and 5V un-
der voltages, and issues a power good signal when
they are ready.
