Hi. I have been looking for a multi-phase (3 or 4) controller for a DC-DC application, which has SPI, I2C, or other serial interface so that I can control the duty cycle (PWM) and read back outpt voltage and current. I need the supply voltage to be 18-40v (with different inductors for the higher range), o/p 14-18v, and external switches for high current.
Does anyone know of a suitable device ?
Failing that, I will use a PIC.
