FP5209
FP5209 is Non-Synchronous PWM Boost Controller manufactured by Feeling Technology.
Non-Synchronous PWM Boost Controller
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 pensation network minimizes external ponent 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.
