STEVAL-ISA143V1, 12V, 150 W Resonant Converter with Synchronous Rectification Evaluation Board based on L6563H, L6699 and SRK2000

STEVAL-ISA143V1, System Evaluation Board is made up of two stages: a front-end PFC using the L6563H, an LLC resonant converter based on the L6699 and the SRK2000, controlling the SR MOSFETs on the secondary side. The SR driver and the rectifier MOSFETs are mounted on a daughter board. The L6563H is a current mode PFC controller operating in transition mode and implements a high voltage startup source to power on the converter. The L6699 integrates all the functions necessary to properly control the resonant converter with a 50% fixed duty cycle and work with variable frequency. The output rectification is managed by the SRK2000, an SR driver dedicated to LLC resonant topology
