Description
The IR3870M 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 IR3870
a space-efficient solution that delivers up to 10A
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. The combination of the gate drive
charge pump option and constant on time control
allow efficiency optimization in the whole output
current range, making this device 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.
