Description

The IR3820 SupIRBuck

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

startup time, power good threshold and current

limit, the IR3820’s fixed 600kHz switching

frequency allows the use of small external

components.

The IR3820 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.

HIGHLY INTEGRATED 12A
