PI parts for low input voltage buck or flyback convertor

2 posts / 0 new

I am searching for a device that can work as a wide input range step down convertor with the following spec's:
- Input voltage: ~10 .. 150V DC
- Output voltage: 3.3V, 0.5A

I have searched across multiple PI devices, but I find minimum voltages of ~70V or 50V.

Also PI Expert tool does not give me any solutions.

Is there a parametric table, or a way to select devices that could fit?

Hi e.jongerius,

Can I ask what is the application of this?

You can check DPA-Switch however it's VDC input range is from 16-75VDC.
