UCC33420: Isolated Power Supply Recomendation for 24 to 96V Battery System

Tool/software:

Hello,

I entered a random product code just to get a product recommendation.

We are looking for an isolated supply for a 3-phase motor driver system that steps down from a vehicle battery voltage range of 24V to 96V to 12V output, providing 4A source and 8A sink gate driver per phase, and using 8 FETs in parallel per phase.

Can you recommend a suitable isolated DC-DC converter for this system?

Best regards,

Egemen

Hi Egemen,

I recommend checking the Motor Driver product section of ti.com and look for any specific isolated power supply that fits your requirements. Link is here Transforming motor control designs | TI.com

As a personal recommendation, I suggest looking into the UCC14xxx-Q1 family, which are DC/DC isolated integrated bias supply for gate driver applications that can deliver 1.5W nominal power. As an examples, I recommend UCC14241-Q1 24V/12V 1.5W bias supply.

Thank you

Hello,

According to the system I mentioned, wouldn't 1.5W be insufficient?

Is there another product you could recommend?

Best regards,
