STNRG011TR

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 800V rated startup generator and a sophisticated digital engine, that manage optimal operation of three blocks. 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.

• Onboard 800V 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 feedforward, 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 halfbridge brown-out protection
• Complete set of half-bridge protections
