Does anyone know of a chip that generates a multi-phase (interleaved) PWM, with the PWM controlled via SPI/I2C/CAN or other serial interface ? I want to build a multi-phase flyback converter to dump energy across 3 isolation transformers (common output). Multiphase to reduce input current ripple for a higher power application. Ideally, this device should have 2 ADC channels readable via the serial port. I will have to code for a PIC if I can't find an off the shelf device.
