TPS53659: How to terminate the input current sense pins when not used

Part Number: TPS53659

Hello,

How do you terminate the Vin_CSIN and CSPIN pins when you are not monitoring the input current? Do you connect them together or terminate each pin to ground, or something else?

Thanks,

Chuck Sampson

    Hi Chunk,

    Please tie those pin together and to the VIN before input inductor.

    If there is no input inductor, please connect to the power stage input caps.

    Either case above, adding 1x 1uF capacitor close to controller side for decoupling.

    Thanks
