High efficiency isolated offline LED driver with 11 W fixed output and high PF based on HVLED815PF (EU input range)

STEVAL-ILL055V1

 
Overview

The STEVAL-ILL055V1 is an isolated SMPS designed in high power factor flyback topology. It generates a 640 mA nominal output current, delivering up to 11 W of output power and provides a cost-effective and space-saving solution. This product evaluation board is based on the HVLED815PF, a monolithic converter integrating both an 800 V avalanche-rugged MOSFET and PWM controller in a single package.
