Part Number: TPSM5D1806EVM
Other Parts Discussed in Thread: TPSM5D1806,

Hello,

my name is Namhoon Lee.

I would like to purchase the TPSM5D1806 Power Module Evaluation Module.

Is this board capable of bidirectional voltage output?

If so, please tell me the circuit configuration.

What is meant by bidirectional voltage output?

The TPSM5D1806 is two step down converters capable of two outputs that can source upto

6A each and also can be configured as a 2 phase to 1 output can source upto 12A.

Both configurations step a positive voltage down to a lower voltage positive voltage which are demonstrated in the datasheet.

Each channel can sink upto a typical -2.8A in each channel

The TPSM5D1806EVM board has two output ports.
I wonder if one can output +5V and the other -5V.

If the current EVM board cannot output bivalent voltage, please let me know if it is possible by modifying the circuit inside the board.

Do you understand?

In conclusion, I want to output +5V and -5V from the EVM board.
Tell me how to do it.

If you are attempting to invert a positive input to a negative output similar to the links

To use a step down converter as a inverting supply, you are grounding the "output" and use the ground as the negative output.

The ground is common for both channels. The TPSM5D1806 will not support positive and negative output voltages
