STEVAL-ISC002V1

Resonant LCC 90 W notebook power adapter

based on the L6599 and STP12NM50N

Features

at 264 V

Description

This demonstration board is a 90 W wide-range

mains AC-DC adapter which is power factor

corrected. Its electrical specifications are suitable

for typical high-end portable computer power

adapters. The particular benefits of this design

are the very low no-load input consumption (<0.5

W) and the very high global efficiency.

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

that makes use of the L6599 resonant controller.
