Part Number: UCD3138064A

Can the UCD3138064A control 6 phases interleaved power stages using DPWM0A, DPWM0B, DPWM1A, DPWM1B, DPWM2A, DPWM2B? Please verify if the phase trigger can be used between DPWM0A,0B,1A,1B,etc...

yes, you can control 6 phase interleaved boost converter, each phase will be interleaved by 60 degree. To interleaved DPWM0A and 0B by 60 degree, you can set DPWM0 to multi mode, set event1=0, and set event3=(1/6)*period. The maximum duty cycle will be limited to 83%. The interleave between DPWM0 and DWPM1 is achieved by phase trigger register.
