TPS23861: Manual mode

Part Number: TPS23861

Hi Ti

We set TPS23861 to manual mode.          

When the output is loaded, there will be 48V output.           

But when no load, the output 48V can only last one second, and then it drops to 0.          

Is there a way to set no load and keep 48V output all the time?

Thank you.

Jerry

    Hi Jerry,

    Can you check the register setting of 0x13? If DC disconnect is enabled, it is expected that the port shut off when the load is removed. If you want the port to be kept on, please disable the DC disconnect in register 0x13. Thanks. 

    Best regards,
