Product overview
Description
The STNRG012 embodies a multi-mode (Transition-Mode and DCM) PFC controller, a high-voltage double-ended controller for LLC resonant half-bridge, an 800 V-rated start-up generator and a sophisticated digital engine that manage optimal operation of three blocks.
The STNRG012 manages both input line AC or DC.
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.
The power system and the control algorithms are managed by an 8 bit core with dedicated fast peripherals (SMED). Optimized digital algorithms together with HW analog IPs are implemented to guarantee very high performance, BOM optimization and robustness.
The digital algorithms are stored in an internal ROM memory and all key application parameters can be stored into a device’s NVM memory during production phase, allowing wide configurability and calibration.
The device can also externally communicate through a 2-pin UART, allowing monitor function, black box storing into an external flash and software patch upload from the external flash.
