Non-Synchronous PWM Boost Controller
FP5209
General Description
The FP5209 is a boost topology switching regulator for wide operating voltage applications. It
provides built-in gate driver pin, EXT pin, for driving the external N-MOSFET. The internal
compensation network minimizes external component counts, and the non-inverting input of error
amplifier connects to a 0.6V precision reference voltage. The FP5209 have internal soft start function.
The FP5209 is available in the small footprint SOT23-5L package to fit in space-saving PCB
layout for miscellaneous application fields.
Features
Wide Supply Voltage Operating Range: 2.4 to 5.5V
Precision Feedback Reference Voltage: 0.6V (±2%)
Shutdown Current: <1μA
Internal Fixed PWM frequency: 550KHz
Internal Soft Start Function :7ms (SS)
Over Voltage Protection
Package: SOT23-5L
Duty Cycle: PWM/PFM Switching Control Circuit (15%~90%)
