TPS22810: How to control with Arduino Due

Part Number: TPS22810

I want to control VOUT with Arduino Due. I connected EN/UVLO and digital pin (No.29) of Arduino Due directly. But, I can not control. Although, the digital pin was low, VOUT pin output high voltage from VIN pin. please teach me why I can not control.

    Hi User, 

    Thanks for reaching out on E2E!

    Can you share a schematic or block diagram of your application? Do you have an output load on the TPS22810? 

    The reason why I'm asking is because the TPS22810 does not have a QOD (quick output discharge) functionality. This means, if there is no resistive load on the output, the output will remain high when the switch is off, if you have any load capacitance. 

    Thanks,

    Thanks,

    Arthur Huang
