TYPICAL EFFICIENCY AND POWER LOSS CURVES
PVin = 5.0V, Vcc = 5.0V, Io = 0A‐4A, Fs = 600KHz, Room Temperature, No Air Flow. Note that the efficiency and power loss
curves include the losses of IR3897, 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.
