Hi All,

I want to know the efficiency of the LM5140-Q1.

Data sheet is only up to 5A.

Please teach me the efficiency of 10A.

1)Vin=16V Vout=8V

2)Vin=16V Vout=5V

Best Regards

Hello Hayashi-san,

I will forward your question to the appropriate engineering staff who can answer your question, which properly belongs in the Non-Isolated DC/DC Power Forum.

Regards,

Ulrich

Koji,

VIN 16V, VOUT1 5V, VOUT2 8V and a 10A load on each output, operating at 2.2MHz, the efficiency will be approximatly 86%. I do not have measured data for this application, I used the Quickstart calculator which can be found on the web.
