UCC28700: ucc28700

Part Number: UCC28700

Hi,

I would like to know the changes that are necessary to make to get an output of 24V and 2A. I just need to change the resistances related to voltage sense in UCC28700, maintaining the same transformer, or do I need to change both?

If there is already a sugestion in how to change the default circuit to obtain a 24V and 2A output I would be happy to take a look, if possible.

Best regards,

Hello,

There are many tools at your disposal to help you determine how to do a 24 V to 2 A output flyback design.

1. Webex Design tool that can be found on the following web page. https://www.ti.com/product/UCC28700?keyMatch=UCC28700&tisearch=search-everything&usecase=GPN#design-development##design-tools-simulation

2. A reference design library where you can enter you input and output power requirements to see if there is an exising design that already meets your power needs. The following link will bring you to a reference design libary. https://www.ti.com/reference-designs/index.html#search?keyword=UCC28700

3. The following link will bring you to an application note that goes through a step by step design process of using the UCC28700 in an offlline flyback design. https://www.ti.com/lit/pdf/slua653

Mike
