FP5108
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.
Features
Wide Supply Voltage Operating Range: 1.8 to 12V
Precision Feedback Reference Voltage: 0.5V 2%)
High Speed Oscillator Frequency: 600KHz max.
Low Current Consumption: Operation Mode 5.5mA
Low Current Consumption: Shutdown Mode 1μA
Programmable Soft Start Function (SS)
Short Circuit Protection Function (SCP)
Totem-pole Output
Shutdown Function with Adjustable Driving Current
Package: SOP-8L, SOP-8L (EP), TSSOP-8L and MSOP-8L
Applications
Low Input Voltage DC / DC Converter
Battery used Equipment
Low Output Voltage DC / DC Converter
