... An internal soft-start function controls rise rate of the output voltage to limit the current surge at start-up. The typical soft-start interval is about 2ms. Current Limit The APE8957 monitors the current via the output NMOS and limits the maximum current to prevent load and APE8957 from damage during overload or short circuit VOUT = 0 R1/R2) ...

... 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. ...
