Description

The STNRG011A 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 STNRG011A manages only input line AC.

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 a very high

performance, BOM optimization and robustness.

The digital algorithms are stored into an internal ROM memory and all key application parameters can be stored

into a device's NVM (non-volatile memory) memory during the production phase allowing wide configurability and

calibration.

The device can also externally communicate through a 2-pin UART, allowing the monitoring function, the black

box storing into an external E2PROM and the software patch upload from the external E2PROM.
