integrated and highly efficient DC/DC regulator.
The onboard switching controller and MOSFETs
make the IR3822 a space-efficient solution,
providing accurate power delivery for low output
voltage applications.
The IR3822 operates from a single 4.5V to 14V
input supply and generates an output voltage
adjustable from 0.6V to 0.75*Vin at loads up to 4A.
A versatile regulator offering programmability of
startup time, power good threshold and current
limit, the IR3822’s fixed 600kHz switching
frequency allows the use of small external

The IR3822 also features important protection
functions, such as Pre-Bias startup, hiccup
current limit and thermal shutdown to provide the
required system level security in the event of fault
conditions.
