FUNCTION DESCRIPTION(Cont.)
Output Voltage Regulation
An error amplifier working with a temperature compensated 0.8V reference and
an output NMOS regulates output to the preset voltage. The error amplifier designed with
high bandwidth and DC gain provides very fast transient response and less load
regulation. It compares the reference with the feedback voltage and amplifies the
difference to drive the output NMOS which provides load current from VIN to VOUT.
Under Voltage Protection (UVP)
The APE8957 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 APE8957 starts a new soft-start to regulate output.
Thermal Shutdown
A thermal shutdown circuit limits the junction temperature of APE8957. When the
junction temperature exceeds +150°C, a thermal sensor turns off the output NMOS,
allowing the device to cool down. The regulator regulates the output again through
initiation of a new soft-start cycle after the junction temperature cools by 50°C, resulting
in a pulsed output during continuous thermal overload conditions.
