UCC2804: Linear model DCM flyback and current peak mode

baptiste lhuillier

Part Number: UCC2804

Tool/software:

Hello,

I want to use the UCC2804 to control flyback converter.

The example in the datasheet is about CCM flyback with current peak mode.

I'm looking for an example of DCM flyback with current peak mode. I can read it's easier to stabilize but no more information.

That'll help me to justify loop stability

Do you know where can I find example of this modelization?

Thanks

Hi,

Please clarify what is DCM flyback with current peak mode. Do you mean peak current mode control flyback in DCM operation?

Yes, exactly

Hi,

Refer to this how to design a peak current mode flyback in DCM.

Hi,

Thanks for yout feedback

I've read the handbook but i didn't found how stabilize the converter.

I'm not a specialist, so i 'd like to find example and that'll help me to justify loop stability

Hi,

This below helps you to know how to do converter stabilize, which in power supply called loop compensation.
