integrated and highly efficient DC/DC regulator.
The onboard switching controller and MOSFETs
make the IR3820 a space-efficient solution,
providing accurate power delivery for low output
voltage applications.
The IR3820 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
12A.
A versatile regulator offering programmability of
