Part Number: LM5157-Q1

This design is generated with online Webench tool. It is set for 36V and 1.5A out at peak consumption.

My question is, why this design draw ~110mA(at 12Vin) when out is not under any load?

....Still didn't test it under load, first i wont to figure out why is this current drawn at input from supply.

    Hello Stefan, 

    Thanks for reaching out. Did you get this value for the input current in no load from the WEBENCH tool?  Or did you measure this value in no load? If you measured it, did you have a multimeter in series with your power supply? 

    Kind regards,

    Elisabetta
