Dual output, 6A/Phase, Highly Integrated SupIRBuck^®

IR3892

Single-Input Voltage, Synchronous Buck Regulator

FEATURES

DESCRIPTION

The IR3892 SupIRBuck^®is an easy-to-use, fully

integrated and highly efficient DC/DC regulator. The

onboard PWM controller and MOSFETs make IR3892

a space-efficient solution, providing accurate power

delivery for low output voltage.

• Single 5V to 21V application

• Wide Input Voltage Range from 1V to 21V with

external Vcc

• Output Voltage Range: 0.5V to 0.86*PVin

• Dual output, 6A/Phase

IR3892 is

versatile regulator which offers

• Enhanced Line/Load Regulation with Feed-

Forward

programmability of switching frequency and a fixed

current limit while operating in wide input and output

voltage range.

• Programmable Switching Frequency up to 1.0MHz

• Internal Digital Soft-Start

• Enable input with Voltage Monitoring Capability

The switching frequency is programmable from

300kHz to 1.0MHz for an optimum solution.

• Thermally compensated current limit and Hiccup

Mode Over Current Protection

It also features important protection functions, such as

Over Voltage Protection (OVP), Pre-Bias startup,

hiccup current limit and thermal shutdown to give

required system level security in the event of fault

conditions.

• External synchronization with Smooth Clocking

• Precision Reference Voltage (0.5V +/-1%)

• Seq pin for Sequencing Applications

• Integrated MOSFETs, drivers and Bootstrap diode

• Thermal Shut Down

APPLICATIONS

• Open Feedback Line Protection

• Sever Applications

• Over Voltage Protection

• Netcom Applications

• Interleaved Phases to reduce Input Capacitors

• Monotonic Start-Up

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

• Set Top Box Applications

• Storage Applications

• Small Size 5mm x 6mm PQFN

• Embedded telecom Systems

• Distributed Point of Load Power Architectures

• Computing Peripheral Voltage regulators

• General DC-DC Converters

• Lead-free, Halogen-free, and RoHS Compliant
