IR3837MPbF

SupIRBuck

HIGHLY INTEGRATED 14A

SINGLE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR

Features

Description

•

Greater than 96% Maximum Efficiency

The IR3837 SupIRBuck^TMis 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.

Single 16V Application

Single 5V Application

Wide Output Voltage Range: 0.6V to 0.9*Vin

Continuous 14A Load Capability

Programmable Switching Frequency up to 1.5MHz

Internal Digital Soft-Start

IR3837 is a versatile regulator which offers

programmability of switching frequency and

current limit while operates in wide input and

output voltage range.

Enable Input with Voltage Monitoring Capability

Hiccup Mode Over Current Protection

Internal LDO

External Synchronization

Enhanced PreBias Start up

The switching frequency is programmable from

250kHz to 1.5MHz for an optimum solution.

External Reference for Margining Purposes

Input for Tracking Applications

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.

Integrated MOSFET Drivers and Bootstrap Diode

Operating Junction Temp: -40^oC <Tj<125^oC

Thermal Shut Down

Power Good Output with Tracking Capability

Over Voltage Detection Feature

IR3837 offers margining capability through Vref

pin. During the margining operation, PGood

tracks Vref via feedback to ensure correct status

of the output voltage.

Pin Compatible with 6A and 10A Versions

Small Size 5mmx6mm PQFN, 0.9 mm Height

Lead-free, Halogen-free and RoHS Compliant

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.

Applications

•

Netcom and Telecom Applications

Data Center Applications
