STMicroelectronics STNRG011
The STNRG011 embodies a multi-mode (transition-mode and DCM) PFC controller, a high- voltage double-ended 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 device comes in a 20-pin SO package and offers an advanced solution for power- factor-corrected highefficiency converters supposed to comply with the most stringent energy saving regulations. The power system and the control algorithms are managed by an 8-bit core with dedicated fast peripherals (SMED).| Part No. | STNRG011 |
