LM3150: LM3150

Part Number: LM3150

Hi,

I am working on bringing up a board that has an LM3150 configured to convert a 24V input to 12V output. Upon application of power Vin=Vout = 24V. The schematic is attached in PDF format. Any idea concerning why this is happening would be appreciated.

Thanks,

Jeff

Jeff,

There is an error in your schematic, SW node is the node between the two FETs and the inductor, that needs to be connected to the IC SW pin.

I'm not even sure how the high-side FET turned to let VOUT=VIN in that case.

Let me know if you have further issues,

Orlando,

Thank you very much. I don't know how that was missed.

You have been very helpful.
