Digital Power Supply Applications/Reference Design

Other Parts Discussed in Thread: UCD3138

Hi TI Experts,

For the TI digital power supply, is there any reference design available?

The specifications required as below:

- Output power >18W

- Able to generate +/- supply (+/-12V in this case)

I came across the UCD3138. May i know is there any starter kit or evaluation board available?

For microchip, they does have the Digital Power Supply Starter Kit

- dsPIC33F family

Your advice is appreciated

Thanks,

Br,

  • Normally we would not recommend the UCD3138 family for an 18W 12 volt supply unless you have needs for isolation, control, monitoring, and/or efficiency. If you can tell us what your input voltage is and whether you need special isolation, control, monitoring and/or efficiency, or if you just want to learn digital power, we may be able to give you some guidance. You can do up to 4 rails with the UCD3138 in buck/boost mode, but we don't have an EVM for those applications.

    At 18 W, depending on your input voltage, you may be able to get a configurable but preprogrammed chip with integrated switches, making your parts and system costs much lower than with either the UCD or the Microchip. I don't know enough about those to know what to recommend, if that is what you need.
