Application note
STEVAL-ISA080V1 90 W-HB LLC resonant converter
based on the L6585DE combo IC

Introduction
This application note describes the performance of a 90 W, wide range mains, power factor
corrected AC-DC power supply demonstration board.
The architecture is based on a two-stage approach: a front-end PFC pre-regulator and a
downstream multi-resonant half bridge converter. Both stages are controlled by the new IC -
L6585DE- which integrates PFC and half bridge control circuits and the relevant
