Application note
19 V - 90 W adapter with PFC for laptop computers using the
L6563H and L6599A
Introduction
This application note describes the performance of a 90 W, wide-range mains, power-factorcorrected, AC-DC adapter demonstration board. Its electrical specification is tailored on a
typical hi-end portable computer power adapter.
The architecture is based on a two-stage approach; a front-end PFC pre-regulator based on
the L6563H TM PFC controller and a downstream LLC resonant half-bridge converter using
the new L6599A resonant controller. Thanks to the chipset used, the main aspects of this
design are very high efficiency, compliance with ENERGY STAR® Eligibility Criteria (EPA
rev. 2.0 EPS), and very low input consumption at no-load (
