Low Voltage DC / DC Buck Controller
FP5108
General Description
The FP5108 is a buck topology switching
regulator controller for low operating voltage applications field.
The FP5108 includes a totem-pole single output stage for driving
PNP transistor or P-MOS, high precision reference (0.
5V) for comparing output voltage with feedback amplifier, an internal duty control for controlling the maximum duty cycle, programmable soft start with short circuit protection and external shutdown control.
