DI-152 update

Posted by: Simon Peacock on 11/21/2025

Hi All

I was looking at the app note (again), but the TinySwitch-iii is no longer available.

Can you simply replace the chip with a TinySwitch TNY290P ?

Thanks

Simon

Hello Simon,

The TinySwitch-3 TNY280P is replaceable with the TinySwitch-4 TNY290P.
