Description
The IR3821
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 IR3821 a space-efficient solution,
providing accurate power delivery for low output
voltage applications.
The IR3821 operates from a 4.5V to 14V input
supply
and
generates
adjustable from 0.6V to 0.75*Vin at loads up to 7A.
an
output
voltage
A versatile regulator offering programmability of
startup time, power good threshold and current
limit, the IR3821’s fixed 600kHz switching
frequency allows the use of small external
components.
The IR3821 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
