Configurable high-efficiency interleaved PFC digital controller
ST has extended its portfolio of digital controllers with the STNRGPF01, a three-channel interleaved CCM PFC controller. Ideal for high power applications (above 1 kW), it delivers the flexibility and high efficiency of digital power without the technical challenges and time to develop custom DSP code. It can be easily and quickly configured using ST’s eDesignSuite online design environment. Simply enter the converter specs and run the configurator to generate the schematic, BoM, and downloadable firmware to configure the IC.
- Up to 3-channel interleaved boost PFC
- Configurable phase-shedding strategy to maintain high efficiency across all load conditions
- Flexible frequency (up to 300 kHz) to control either an IGBT or MOSFET output stage
- I2C and UART interfaces for monitoring and control
