IR3843WMPbF

HIGHLY EFFICIENT

SupIRBuck

INTEGRATED 2A SYNCHRONOUS BUCK REGULATOR

Features

Description

•

Wide Input Voltage Range 1.5V to 16V

Wide Output Voltage Range 0.7V to 0.9*Vin

Continuous 2A Load Capability

The IR3843W SupIRBuck^TMis an easy-to-use,

fully integrated and highly efficient DC/DC

synchronous Buck regulator. The MOSFETs co-

packaged with the on-chip PWM controller make

IR3843W a space-efficient solution, providing

accurate power delivery for low output voltage

applications.

Integrated Bootstrap-diode

High Bandwidth E/A for excellent transient

performance

•

Programmable Switching Frequency up to 1.5MHz

Programmable Over Current Protection

PGood output

IR3843W is a versatile regulator which offers

programmability of start up time, switching

frequency and current limit while operating in

wide input and output voltage range.

Hiccup Current Limit

Precision Reference Voltage (0.7V, +/-1%)

Programmable Soft-Start

Enable Input with Voltage Monitoring Capability

Enhanced Pre-Bias Start-up

The switching frequency is programmable from

250kHz to 1.5MHz for an optimum solution.

Seq input for Tracking applications

-40^oC to 125^oC operating junction temperature

Thermal Protection

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.

Multiple current ratings in pin compatible footprint

5mm x 6mm Power QFN Package, 0.9 mm height

Lead-free, halogen-free and RoHS compliant
