|
for a LED driver, how to simulate its efficiency?that is,how to get the curve of efficiency and vdd?
for example,Cp2133 has two operation mode:1X and 1.5X,when vdd falls to 3v,it converts to 1.5X mode from 1X mode;i want to know,how to get the curve of efficiency and vdd when vdd falls from 5V to 2V?pls help me.
