Request for Flyback Controller Recommendation for 24V Input
Posted by: Manjesh

Hi Team,
We are developing an isolated flyback converter with a nominal input voltage of 24 VDC and an output of 18 VDC, delivering between 20 W to 30 W of power.
In a related project, we have used the InnoSwitch3-EP family successfully. I initially considered using the same family for this design; however, the PI Expert tool does not support low-voltage inputs, and I believe that using a controller designed for universal AC inputs may not be ideal in this case.
Could you please recommend a suitable flyback controller with an integrated MOSFET that is optimized for low-voltage DC input (around 24 V)?

Hello Manjesh,
Good morning and thank you for continuously choosing Power Integrations.
I highly suggest using our DPA switch for low-voltage DC applications. You just need to ensure that the copper heatsink of the IC is large enough to dissipate the heat generated by the IC. Kindly refer to the attached file for an initial design that corresponds to your input and output requirements. If you also wish to modify and play around with other components and parameters, you can click the link below, and it will redirect you to our PI Expert Online tool.

I hope the information above helps. Let me know if you need further assistance or have any more questions or concerns.
Once again, thank you for using Power Integrations devices in your projects. We really appreciate it. I wish you a great day ahead!
Best regards,
Tommy
