TYPICAL EFFICIENCY AND POWER LOSS CURVES

PVin = 12V, Vcc = External 5V, Io = 0A-6A, Fs = 600 kHz, Room Temperature, No Air Flow. Note that the efficiency and power

loss curves include the losses of IR3898, the inductor losses and the losses of the input and output capacitors. The table

below shows the inductors used for each of the output voltages in the efficiency measurement.
