TPS56637: Light load operation

Takashi Onawa

Part Number: TPS56637

Hi Team,

My customer would like to use TPS56637 in very light load condition such as 0.5A(Max) in order to minimize BOM.
Are there any concern in this use case? I think no issue as long as they use FCCM mode though...

Hi Takashi,

The OC limit of TPS56637 is fixed and much higher than the max current in your application. Except for this point, if the OC value is not important for your customer's application, I think there's no obvious concern.
