The STNRG011TR embodies a multi-mode (transition-mode and DCM) PFC controller, a high-voltage double-ended controller for the LLC resonant half-bridge, an 800V rated startup generator and a sophisticated digital engine, that manage optimal operation of three blocks. The digital algorithms are stored into an internal ROM memory and all key application parameters can be stored into a device's NVM (non-volatile memory) memory during the production phase allowing wide configurability and calibration.
