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.
