STEVAL-ISC002V1
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.
