Original question:

TPS65400: PMIC

TPS65400: Power management forum

Jing chen
Prodigy 30 points
Part Number: TPS65400

Tool/software:

We have developed a power module using the TPS65400 PMIC to power the XC7Z020 Zynq SoC. The module includes a provision for a 5x2 header compatible with USB-to-Any interface for configuration and monitoring via the Fusion Digital Power Designer tool.

All four power rails (SW1 to SW4) have been configured with the following voltage and timing parameters:

  • SW1 – 1.0 V, TON/TOFF Delay: 5 ms

  • SW2 – 3.3 V, TON/TOFF Delay: 0 ms

  • SW3 – 1.8 V, TON/TOFF Delay: 25 ms

  • SW4 – 1.35 V, TON/TOFF Delay: 100 ms

During testing, we confirmed that all voltage rails are physically ON at their respective outputs, verified using a multimeter.

However, the GUI dashboard does not display any Output Voltage (OV) readings — it shows either zero or blank values for all channels. This persists even though the rail voltages are present on the board.

We have attached the configuration file (*.tifsp) for your review.
Kindly advise if any additional registers or telemetry settings need to be enabled to allow proper OV monitoring on the GUI.

    Hi Jing Chen,

    We don't have EVM right now and we are ordering EVM and once we get EVM we will check and get back to you.

    Regards,

    Haseen.

    Hi JIng,

    Attaching the .pptx file including all the steps and output waveforms.

    We can see the delay in the output waveforms as given in the GUI.
