LP87563-Q1: unused output

Part Number: LP87563-Q1

Hi team,

I am using LP87563-Q1 in my current product and would like to utilize this device to the other model.

But the new model only requires 3 outputs and the load current is only around 2.1A.

In this case, Can I remove LC filter of BUCK1 output and leave SW_B1 Open?


  • Hi Shinji,

    Unfortunately that is not possible since the fault detection can trigger when one of the bucks don't have the inductor in place. LP87564 with 4 outputs could be used by disabling one of the outputs. You could leave out the one inductor in that case.
