Description
The IR3876 SupIRBuckTM is an easy-to-use,
fully integrated and highly efficient DC/DC
voltage regulator. The onboard constant on time
hysteretic controller and MOSFETs make
IR3876 a space-efficient solution that delivers up
to 12A of precisely controlled output voltage in
60°C ambient temperature applications without
airflow.
Programmable switching frequency, soft start,
and over current protection allows for a very
flexible solution suitable for many different
applications and an ideal choice for battery
powered applications.
Additional features include pre-bias startup, very
precise 0.5V reference, over/under voltage shut
down, power good output, and enable input with
voltage monitoring capability.
