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 dedicated to this architecture.

Thanks to the AHB topology, the system offers good electrical performance (EPA 2.0

compliant) with a low-voltage and high-current output (12 V - 7.5 A).

The order code for this demonstration board is EVL6591-90WADP.
