Variable Phase-Shifted Full-Bridge PWM Controller (LM5046/UCC28950)

Hello, we are looking for a variable Phase-Shifted Full-Bridge Controller (With Synchronous Rectification) to create a variable DC-DC converter. The LM5046 & UCC28950 controllers have the majority of the features except the ability to directly control by a micro (TMS320F28035/UCD3138). Does TI offer similar PWM controllers that can be controlled by a micro?

The UCD3138 is an Integrated digital PWM controller that can be configured for many different topologies. They have a few application notes and EVM using the device in many configurations including phase shifted full bridge converter. I don't have experience with this device but it may be able to be setup in your configuration. You will have to double check with the digital applications team.

So the appropriate TI applications group sees this you might want to re-post the question with UCD3138. This way the digital applications engineer will see it and will be able to answer your question.

Regards,

I recommend asking on the C2000 forum where the digital power experts reside
