TYPICAL EFFICIENCY AND POWER LOSS CURVES

PVin = 12V, Vin = VCC = 5V, Io=0-16A, Fs= 600kHz, Room Temperature, No Air Flow. 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.
