STMicroelectronics STNRG012 Resonant Controller

STMicroelectronics STNRG012 Resonant Controller combines a multi-mode PFC and a time-shift LLC resonant half-bridge controller. This controller is capable of managing both AC and DC input. The STNRG012 power system and the control algorithms are managed by an 8-bit core with dedicated fast peripherals (SMED). This resonant controller features an on-board 800V start-up circuit and line sense. The STNRG012 resonant controller offers brownout protection and a complete set of half-bridge protections.
