Description
The IR3820A
Sup
IR
Buck
TM
is an easy-to-use,
fully integrated and highly efficient DC/DC
regulator. The onboard switching controller and
MOSFETs make the IR3820A a space-efficient
solution, providing accurate power delivery for
low output voltage applications.
The IR3820A operates from a 4.5V to 14V input
supply
and
generates
adjustable from 0.6V to 0.75*Vin at loads up to
14A.

voltage
A versatile regulator offering programmability of
startup time, power good threshold and current
limit, the IR3820A’s fixed 300kHz switching
frequency allows the use of small external
components.
The IR3820A 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.
Applications
Distributed Point-of-Loads
Server and Workstations
