FP5138B
Non-Synchronous PWM Boost Controller
General Description
The FP5138B is a boost switching regulator controller IC for battery-used applications. The
FP5138B includes a totem-pole output stage for driving NPN transistor or N-MOS, high precision
reference (0.5V) for comparing output voltage by feedback amplifier, precision maximum duty cycle
control, programmable soft start with short circuit protection function and operating mode control
between operation and standby mode.
Features
Wide Supply Voltage Operating Range: 1.8 to 15V
Reference Voltage Precision: 2%
Low Current Consumption: 5.5mA in Operation Mode
Low Current Consumption: 1μA in Standby Mode
High Oscillator Frequency: 1MHz max.
Programmable Soft Start Function (SS)
Short Circuit Protection Function (SCP)
Totem-Pole Output with Adjustable ON / OFF Current (for NPN Transistors or n-Channel MOSFET)
Logic Level Control Stand-by Mode Function
Package: SOP-8L (EP),SOP-8L and TSSOP-8L and MSOP-8L
Applications
Digital Camera
PDA
Portable Equipment
