The STM32 Low Voltage Digital PFC Starter Kit is a complete digital PFC stage controlled by the STMicroelectronics ARM® Cortex®-M4 core-based STM32F334R8T6 or STM32G474RET6 microcontroller. The kit is designed for both analog power supply design engineers and embedded systems engineers who are interested in learning about digital power and digital PFC pre-regulators. The kit allows these users to quickly and easily implement a high performance fully digital PFC pre-regulator power stage in the form of a single phase CCM Boost PFC, or a dual-phase/interleaved CCM Boost PFC.

• Continuous conduction mode Boost converter Power Factor Correction power stage
