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 manages the optimal operation of three blocks.
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 transient response and line adaptive half- bridge brown-out protection
- Complete set of half-bridge protections
