IR3832WMPbF

SupIRBuck

HIGHLY EFFICIENT INTEGRATED

SYNCHRONOUS BUCK REGULATOR FOR DDR APPLICATIONS

Features

Description

The IR3832W SupIRBuck^TMis an easy-to-use,

fully integrated and highly efficient DC/DC

regulator. The MOSFETS co-packaged with the

on-chip PWM controller make IR3832W a space-

efficient solution, providing accurate power

delivery for DDR memory applications.

•

Wide Input Voltage Range 1.0V to 16V

Wide Output Voltage Range 0.6V to 0.9*Vin

Continuous 4A Load Capability

Integrated Bootstrap-diode

High Bandwidth E/A for excellent transient

performance

•

Programmable Switching Frequency up to 1.5 MHz

Programmable Over Current Protection

PGood output

IR3832W is configured to generate termination

voltage (VTT) for DDR memory applications.

Hiccup Current Limit

IR3832W offers programmability of start up time,

switching frequency and current limit while

operating in wide input and output voltage range.

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.

Vp input for DDR 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.

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

Halogen Free, Lead Free and RoHS Compliant
