UC1825 for Active clamp forward application

Mahesh,

Let me look into it, as to what possible solutions are available for active clamp fwd converter and will get back to you.

Hi Ramesh,

Can you tell me the criteria apart from Duty cycle limit for a dual output controller to be used in an active clamp application?
UC1825A-SP has a duty cycle up to 85%. If duty cycle is the limiting factor to be used for the active clamp application, then this device should support although I don't see explicit circuit diagrams.

Hi Ramesh,
Were you able to look into this?

Mahesh,

     For the active clamp configuration you will require the output pulses to be D and (1-D)  or in other words Q and Q_bar outputs.  UC1825 will  have A & B outputs but they are delayed.  thus one can use to implement in push-pull configuration.

In order to use in Active clamp you can only use Output A and add external circuitry to generated (1-D) output.    This can also be done with using UC1843 ( single output) as well.  

      LM5025 is specifically targeted for active clamp topology.
