DESCRIPTION
The IR3892 SupIRBuck® is an easy-to-use, fully
integrated and highly efficient DC/DC regulator. The
onboard PWM controller and MOSFETs make IR3892
a space-efficient solution, providing accurate power
delivery for low output voltage.
IR3892 is a versatile regulator which offers
programmability of switching frequency and a fixed
current limit while operating in wide input and output
voltage range.
The switching frequency is programmable from
300kHz to 1.0MHz for an optimum solution.
It also features important protection functions, such as
Over Voltage Protection (OVP), Pre-Bias startup,
hiccup current limit and thermal shutdown to give
required system level security in the event of fault
conditions.

TYPICAL EFFICIENCY AND POWER LOSS CURVES
PVin = 5V, Vcc = 5V, Io=0-6A, 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 while running a
single channel and disabling the other.
