Hello,

The device contains 4 fusion power peripherals FPP. Each FPP has 2 PWMs. That makes up to 4 rails and 4x2 = 8 phases. I'm still looking for the SEQ pins

Hello sir , thanks for the response , I have a doubt ,but if there is no seperate voltage sense and trip (current trip) for each phase why the design 1A and 1B.if cs 1A is directly connected to comparator, what about CS 1 B its connected to ADC as per data sheet ? And what is the main moto behind this multi phase design ?
