TPS546D24A: VOUT controlled through PMBus

Part Number: TPS546D24A

Hello,

My customer would like to control TPS546D24A output voltage with voltage monitoring of other power line.

It seems that MSP430 can be used for the voltage monitoring and control the TPS546D24A through PMBus.

I have question.

1. Below software can be used for TPS546D24A?

2. Do you have any recommend of MSP430 device or other?

Best regards,

Katsu

    Hi 

        Any micrcontroller or processor with an I2C interface master should be able to communicate with the TPS546D24A. Typically as the TPS546D24A is a high current device, the system should be having a microprocessor already. Doesnt the customer system have this? If your system doesnt have it, a MSP430 with an I2C master port should be able to interface. As the TPS546D24A has circuitry to monitor the voltage and current, the value can be directly read by the MSP430 or the microprocessor. You dont need to use the ADC of the microcontroller/processor.

    For the software, you can use the Fusion Power Designer
