DESCRIPTION
regulator. This product is specifically designed to provide
well supply voltage for front-side-bus termination on
motherboards and NB applications. The IC needs two
supply voltages, a control voltage for the circuitry and a
main supply voltage for power conversion, to reduce
power dissipation and provide extremely low dropout. The
APE8901 integrates many functions. A Power-On-Reset
(POR) circuit monitors both supply voltages to prevent
wrong operations. A thermal shutdown and current limit
functions protect the device against thermal and current
over-loads. A POK indicates the output status with time
delay which is set internally. It can control other converter
for power sequence. The APE8901 can be enabled by
other power system. Pulling and holding the EN pin below
0.3V shuts off the output.
DFN 2x2 packages. That features small size as SOP-8
with an Exposed Pad to reduce the junction-to-case
resistance, being applicable in 2~3W applications.

... The APE8901 monitors the voltage on FB pin after soft-start process is finished. Therefore the UVP is disabling during soft-start. When the voltage on FB pin falls below the under-voltage threshold, the UVP circuit shuts off the output immediately. After a while, the APE8901 starts a new soft-start to regulate output. ...
