Dear Sir/Ms.
The following are the problems encountered by the customer UCC28722 during testing.
Input DC24V Output DC23V Power 20W
When the power is turned on, the output voltage is abnormal, and a triangle wave between 21V and 7.6V will appear in the VDD . DRV will send 3 pulse signals when VDD reaches 21V.
Can you suggest a solution?
Best Regards,
