Other Parts Discussed in Thread: TIDA-00318, UCD3138, UCD3138A
Hi,
TIDA-00381 is very similar to what we plan to do.The key overview of TIDA-00381 is as follows:
That's what I care about most.
So I downloaded the firmware of TiDA-00381 and read the source code.
DPWM2 is configured as the primary driver and as the synchronization master,DPWM0 is configured as the primary driver and as the synchronization slave.
But the output of Filter is not used to phase DPWM0 with respect to DPWM2 at any time.(Dpwm0Regs.DPWMCTRL0.bit.MASTER_SYNC_CNTL_SEL= 0)
So my question is:
1、How does DPWM0 phase shift relative to DPWM2 when ramp up, light load, low output voltage?
2、How does synchronous rectification(DPWM1) work when ramp up, light load, low output voltage?
3、Is there a design document for TIDA-00318?
