Application note
Reference design: 100W high performance, half bridge LLC
multi-resonant SMPS with PFC

Introduction
This note describes the performances of a 100 W, wide-range mains, power-factor-
corrected AC-DC adapter reference board (EVAL6598-100W). The peculiarities of this
design are the high efficiency and the low no-load input consumption. The architecture is
based on a two-stage approach: a front-end PFC pre-regulator based on the L6563 TM PFC
controller and a downstream multi-resonant half-bridge converter using
