Hi, this is a voltage regulator and in the parametrics side of the description it says " Vout is 24V" for AC Input. I have to use it 220V AC Input and 5V Output. Is it possible for this product.

Kindly

Hi Osman,

Thanks for your interest in UCC28881. Yes, it is possible to configure UCC28881 for 5V output. For reference, take a look at section 9.2.1.2.7 of the UCC28881 datasheet for how to configure the output voltage:

I would suggest using webench to get an idea of what the design needs to look like: https://webench.ti.com/appinfo/webench/scripts/SD2.cgi?ID=211426::power::ben.lough@ti.com

Thanks for your comment,

But the real question is; it is possible to get 5V DC output with 220V AC input with pmp11236?

Osman,

There is already a 5V output on PMP11236. There are two outputs: a 24V output from TP3 to TP6 and a 5V output from TP1 to TP2. If you apply 220Vac at TP4 and TP5, you will get 5V at TP1/TP2.
