STMicroelectronics STNRG011, Power Factor Controller, 19 V 20-Pin, SOIC

The STMicroelectronics STNRG011 is the 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 start-up 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 high-efficiency converters supposed to comply with the most stringent energy saving regulations.
