STEVAL-ISA138V1, Evaluation Board Using the L6563H and L6699 19V - 90W Adapter with PFC for laptop computers

STEVAL-ISA138V1, Evaluation Board is a 90W wide-range mains, power-factor corrected, AC-DC adapter. Its electrical specifications are tailored to 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 down-stream LLC resonant half bridge converter using the new L6699 resonant controller. The main features of this design are very high overall efficiency, compliance with ENERGY STAR eligibility criteria (EPA rev. 2.0 EPS), high efficiency even at light load and compliance with the new ErP Lot 6 Tier2 requirements
