FP5209 Overview
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 pensation network minimizes external ponent counts, and the non-inverting input of error amplifier connects to a 0.6V precision reference voltage.
