Hi all

What is the efficiency of LM25141-Q1 in light load mode?

When Vin = 24V, Vout = 12V, Iout = 20mA. How about the efficiency?

Thanks a lot.

Hello Went,

I am assuming that you are using the device in Diode emulation?

Looking at the User guide for the EVM in DEMB, at 18V in and 5V out the efficiency is ~88%. With 12V out, the efficiency may be a point or two higher?

Hope this helps?

David.
