General Description

1 Description 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).

Key Features

Digital combo multi-mode PFC + time-shift LLC resonant half-bridge controller.
Onboard 800 V startup circuit, line sense and X-cap discharge compliant with IEC 62368-1, for reduced standby power.
Enhanced fixed on time multi-mode TM PFC controller with input voltage feed- forward, THD optimizer and frequency limitation.
Complete set of PFC protections.
Time-shift control of resonant half-bridge.
Enhanced burst-mode at light load with fast.
