16A Highly Integrated SupIRBuck
Single‐Input V-o1l1ta-Pge, Synchronous Buck Regulator
PD‐97746
IR3895
TYPICAL EFFICIENCY AND POWER LOSS CURVES
PVin = 12V, Vcc = External 5V, Io = 0A‐16A, Fs = 600kHz, Room Temperature, No Air Flow. Note that the efficiency and
power loss curves include the losses of IR3895, 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.
