Part Number: TIDA-010062 Dear Expert
We have some totem pole PFC design issue need support .
The Q3 ,Q4 of the totem pole is easy to damage during the soft start process. Can the Q3 ,Q4 not be turned on during the PFC start process, and the driver signal…
Part Number: TIDA-010062 Other Parts Discussed in Thread: TMDSCNCD280049C Hi team,
While reviewing documentation for the TIDA-010062, it was confusing how many boards would need to be built and assembled to fully build this design. Within the gerber…

2. Is the voltage loop…
Hi Desheng,
Thanks for your support.
Desheng, Guo said: but there is current spike during input voltage zero crossing.
This current spike does not look like it's because of the voltage zero crossing. Could you help check it again?
Thanks and regards…
Part Number: TIDA-010062 Hello,
When debug our board based on TIDA-010062 SW. The board can only work in fixed 50 or 60Hz.
The function in TTPLPFC_autoStart
if(TTPLPFC_sine_mains.acFreq > 55) { TTPLPFC_sine_mains.acFreq = 60; } else { TTPLPFC_sine_mains…
