FP5209-Non-Synchronous PWM Boost Converter


FP5209 Non-Synchronous PWM Boost Converter
General Description
Download
      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
