TYPICAL EFFICIENCY AND POWER LOSS CURVES

PVin = 12V, Vcc = Internal LDO (4.4V/6.4V), 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.
