Part Number: UCC28C50-Q1
Hi,
In my flyback converter, I am facing an issue with the startup circuit. The converter is a working and tested design; however, the startup circuit is not functioning, and we currently need to provide an external supply…
Part Number: UCC28C50-Q1 Other Parts Discussed in Thread: UCC28C50 Tool/software: I am using the UCC28C50-Q1 in the Flyback circuit, while in low load, I see that PWM of the controller is skipping some cycles here and there.
There is nothing in the…
Hi Yajush,
Yajush Sihag said: Could you please help me identify which components in the schematic could cause the IC to stop generating gate pulses under these conditions?
Seems like COMP is not able to hold above ground for a long time. You can also…
