Reference design: high performance, L6599-based HB-LLC
adapter with PFC for laptop computers

Introduction
This note describes the performances of a 90 W, wide-range mains, power-factor-corrected
AC-DC adapter reference board. Its electrical specification is tailored on a typical hi-end
portable computer power adapter. The peculiarities of this design are the very low no-load
input consumption (<0.4 W) and the very high global efficiency.
The architecture is based on a two-stage approach: a front-end PFC pre-regulator b
