LM5145EVM-HD-20A: high current consumption at 0A loading

Part Number:LM5145EVM-HD-20A

Hi expert,

My customer used LM5145 at their industrial design. They used two LM5145 EVMs to achieve two phase Buck topology. But when they tested with single EVM board, they found out Iin is high about 35mA when Vin=30V and Iout=0A. I also tested another EVM board and the result is the same. Would you kindly help to check if it is normal operation? Thanks a lot!!

Best regards,

Ann Lien
