STNRG011A - STMicroelectronics

STNRG011A PFC and time-shift LLC resonant controller

1 Description The STNRG011A embodies a multi-mode (transition-mode and DCM) PFC controller, a high- voltage doubleended controller for the LLC resonant half-bridge, an 800 V-rated startup generator and a sophisticated digital engine, that manage optimal operation of three blocks. The STNRG011A manages only input line AC. The device comes in a 20-pin SO pa.
