TPS54560B: Short circuit duty setting

Part Number: TPS54560B
Other Parts Discussed in Thread: LMR16030,

Hi Team:

 customer using LMR16030 / TPS54560BDDAR with 28Vin and 24V/3A use case.

 at the beginning , the LMR16030 thermal performance works when test the short circuit test.  but when work normal with 50W~40W load, the thermal is a little higher. 

 Then we decide to change to TPS54560BDDAR,   The duty cycle during short circuit is 7.3%.  meanwhile , we found the LMR16030 duty cycle during short circuit is 3%
 do we have a solution how to reduce the duty cycle during short circuit from 7.3% to 3%?

  • Hello,

    What is the curve you are showing and what are the channel / voltage label for each channel?

    Whatever the short circuit behavior you get from the TPS54560B is set internal and not something that is generally configurable.

    Regards,
