Description
The IR3810 SupIRBuckTM is an easy-to-use, fully
integrated and highly efficient DC/DC regulator.
The onboard switching controller and MOSFETs
make the IR3810 a space-efficient solution,
providing accurate power delivery for low output
voltage applications.
The IR3810 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.
IR3810 can be configured for tracking
applications to generate termination voltage (VTT)
for memory applications.
A versatile regulator offering programmability of
start up time and current limit, the IR3810’s fixed
600kHz switching frequency allows the use of
small external components.
IR3810 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.
