Application note
EVL6591-90WADP: 90 W AC-DC asymmetrical
half-bridge adapter using L6591 and L6563

Introduction
This document describes the characteristics and performance of a 90 W wide range input
AC-DC adapter based on asymmetrical half-bridge topology (AHB).
The converter comprises a two-stage approach: a PFC front-end stage using the L6563 TM
PFC controller and a DC-DC stage that implements the asymmetrical half-bridge (AHB)
topology driven by the L6591, the new PWM controller
