STNRG011A Digital Combo Multi-Mode PFC and Time-Shift LLC Resonant Controller

STMicroelectronics' digital combo controller includes a PFC controller, time shift controller, startup generator, and digital engine

Image of STMicroelectronics STNRG011A Digital Combo Multi-Mode PFC and Time-Shift LLC Resonant ControllerSTMicroelectronics' STNRG011ATR is a digital combo controller that embodies a multimode (transition mode and DCM) PFC controller, a high-voltage double-ended time shift controller for LLC resonant half-bridge, an 800 V startup generator, and a sophisticated digital engine that manages and supervises the previous three blocks. This A version enhances the OM (overload management) feature with an algorithm that increases the frequency when the overcurrent protection is triggered in order to improve the voltage output regulation when this protection is running and avoid unwanted shutdown.
