STEVAL-ISA148V1：19 V - 90 W adapter with PFC for laptop computers based on L6563H and L6599A
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).
