STEVAL-ISA170V1

12V, 150W resonant converter evaluation board with synchronous rectification based on L6563H, L6699 and SRK2001. The 150W converter tailored to a typical specification for an all-in-one (AIO) computer power supply or a high 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 downstream LLC resonant half-bridge converter using the L6699 resonant controller. The L6699 integrates some very innovative functions such as self adjusting adaptive dead time, anti-capacitive mode protection and a proprietary safe-start procedure that prevents hard switching at start-up. The innovative adaptive synchronous rectification controller SRK2001 allows maximum efficiency in all load conditions. The main feature of this power supply is its very high efficiency which is compliant with ENERGY STAR® eligibility criteria for adapters and computers.
