UCC28C45: Pulse on output with no load?

Part Number: UCC28C45

Hi Team,

For the UCC28C45 controller.  Is it normal for the controller to pulse the output during no-load conditions?

 

The first image is with 20mA load, then 40 mA, and the final one that is steady 5V output is 60mA load.

Thanks!

Connor
