Part Number:LM25118
Dear all:
The output of LM25118 is 5V, and the input is also about 5V (PC supplies 5V). The efficiency, I measurement the input voltage, input current, output voltage and output current are measured to calculate efficiency the test results are as follows:
(5.035V*0.496A)/(4.985V*0.673A)=74.4%
is only about 70%.But I think the Data sheet is pretty efficient.
Please help to analyze the possible reasons for the inefficiency.How to improve output efficiency?
