UCC28180: Spec of burst mode

chentsu chung

Part Number: UCC28180

Hi Sir,

I couldn't find any information in datasheet about burst mode.

1.What is the operation frequency of it?

2.What are the exactly conditions for it to enter burst mode?

3.What are the exactly conditions for it to leave burst mode?

Thank you.

Hi C.T.,

There is no special burst mode for UCC28180, it will do a natural burst at extreme light load: the duty generated by control loop sometimes is zero.
