STEVAL-ISA148V1
19 V - 90 W adapter with PFC for laptop computers based on
L6563H and L6599A
Data brief
Description
The STEVAL-ISA148V1 is a 90 W, wide range
mains, power factor corrected, AC-DC adapter
system evaluation 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 L6563H TM PFC controller and a downstream
LLC resonant half-bridge converter using new
L6599A resonant controller. Thanks to the
chipset used, the main characteristics 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
(< 0.3 W).
