UCD3138: UCD3138 Communication/Interface

Part Number: UCD3138

Hi TI Experts,

I have customer that plan to use UCD3138 for the Digital Power Supply project. 

This is the new project as i also not so familiar with the digital power supply.

From the datasheet and EVM, I came across this PMBus and UART.

> May i know is UCD3138 need to operate as host/slave with other MCU?

> Can UCD3138 work independently?

> If no, our plaform is using FPGA, is there any problem on the interface for PMBus?

> If not using PMBus, can it change to I2C?

Currently they are evaluating the UCD3138HSFBEVM-029.

Please advice.
