LM5176: 24Vout/4A

Part Number: LM5176

Hi Sir 

My SPEC is VIn = 10.8V~36V  to 24Vout/4A

I can use webench to simulation around a few day ago 

But I can't use webench to simulation today for this SPEC

Below have attached file ,but these component value will cause Vout swing and unstable for 2A~4A

    Hi Kai,

    Thank you for your interests in the LM5176. We will investigate this and get back to you.

    Thanks,

    Hi Kai,

    I took a look and it seems the Webench selectable MOSFETs on the webench referenced PCB (which is based on one of our EVMs) may become overheated. This may not be a real problem when you do your own layout. In such cases, you can reduce the ambient temperature to -40C to create a webench design. You can change to different FETs or layout in your own circuit.

    Thanks,
    Youhao
