TPS23755EVM-894: Transformer Design

Part Number: TPS23755EVM-894
Other Parts Discussed in Thread: TPS23758EVM-080, TPS23758

Hi TI

We refer to TPS23755EVM-894 to design PD.

Can transformer parameters be provided?           

We want to design 48V input, 5V/2A output and 48V input, 12V/1A output .          

These two designs want to be designed with EP-10 core.

Thanks.

Jerry

    Hi Jerry,

    For 13W applications an EP10 core will be too small. Thermal performance would not be good.

    For the 5V solution we recommend a synch flyback in order to have good regulation. Therefore for 5V solution using primary side regulation, TPS23758 is recommended. Please see TPS23758EVM-080. 

    I will send friend request and we can discuss transformer offline.

    Thanks!
