DC-DC converter (60W)

Posted by: sabastiankk on 07/06/2012

Is there any Device will support for DC-DC converter 60W (12V/5A) and the input is 22-26VDC.

I have checked the design samples, i found a device, DPA426A, Will it support for 24VDC.

Comments

If the line sense pin connected to source, the part has no problem with 24V input. The only problem for this application is thermal. Heatsink is needed for thermal dissipation.

thanks for using PI part.

Please see the attached schematic and let me know the feedback, i will provide more heat sink area.

For your application, flyback is much worse than forward. You have to use forward topology and enough heatsink if you want to designed with DPA426.
