The IR3837 SupIRBuck TM is an easy-to-use, fully
integrated and highly efficient DC/DC regulator.
The onboard PWM controller and MOSFETs
make IR3837 a space-efficient solution, providing
accurate power delivery for low output voltage
applications.
IR3837 is a versatile regulator which offers
programmability of switching frequency and
current limit while operates in wide input and
output voltage range.
The switching frequency is programmable from
250kHz to 1.5MHz for an optimum solution.
It also features important protection functions,
such as Pre-Bias startup, hiccup current limit and
thermal shutdown to give required system level
security in the event of fault conditions.
IR3837 offers margining capability through Vref
pin. During the margining operation, PGood
tracks Vref via feedback to ensure correct status
of the output voltage.
Applications
? Netcom and Telecom Applications
? Data Center Applications
? Distributed Point of Load Power Architectures
The internal LDO enables the device to operate
from a single supply. This internal LDO can be
bypassed when an external bias voltage is
available.
