... APL5912 from damages during overload or short- circuit conditions. Under-Voltage Protection (UVP) The APL5912 monitors the voltage on FB pin after soft- start process is finished. Therefore the UVP is disable during soft-start. When the voltage on FB pin falls below the under-voltage threshold, the UVP circuit shuts off the output immediately ...

... During load transients, the output capacitors, depending on the stepping amplitude and slew rate of load current, are used to reduce the slew rate of the current seen by the APL5912 and help the device to minimize the variations of output voltage for good transient response. For the applications with large stepping load current, the low-ESR bulk capacitors are normally recommended ...
