TYPICAL EFFICIENCY AND POWER LOSS CURVES

PVin = Vin = 12V, VCC = Internal LDO, Io=0-35A, Fs= 600kHz, Room Temperature, LFM=200. Note that the

losses of the inductor, input and output capacitors are also considered in the efficiency and power loss curves.

The table below shows the indicator used for each of the output voltages in the efficiency measurement.
