Geneva. STMicroelectronics’ developed the STNRG011A digital power combination controller for 90W to 300W power supplies to be utilized in power adapters, chargers, television energy, and lighting power supplies. The STNRG011A embeds a power-factor correction (PFC) controller, LLC resonant half-bridge controller, 800V startup circuitry, and supervisory engine featuring an 8-bit core and dedicated peripherals, with digital algorithms accumulated within internal ROM.
Highlights of the multi-mode PFC controller include input-voltage feedforward, a distortion optimizer, and frequency limitation. An improved overload management algorithm enhances switching frequencies when protection is prompted, as well as, preserving output-voltage control for preventing shutdowns.
Further features include:
- On-chip non-volatile memory
- 2-pin UART port
- PFC
- Half-bridge protection
- X-capacitor discharge circuitry compliant with IEC 62368-1
