Single-Input Voltage, Synchronous Buck Regulator

35A Highly Integrated SupIRBuck^®

IR3846

FEATURES

DESCRIPTION

The IR3846 SupIRBuck^®is an easy-to-use, fully

integrated and highly efficient DC/DC regulator. The

onboard PWM controller and MOSFETs make IR3846

a space-efficient solution, providing accurate power

delivery for low output voltage and high current

applications.

 Single 5V to 21V application

 Wide Input Voltage Range from 1.5V to 21V with

external Vcc

 Output Voltage Range: 0.6V to 0.86*PVin

 0.5% accurate Reference Voltage

 Enhanced line/load regulation with Feed-Forward

 Programmable Switching Frequency up to

IR3846 is

versatile regulator which offers

1.5MHz

programmability of switching frequency and current

limit while operating in wide input and output voltage

range.

 Internal Digital Soft-Start

 Enable input with Voltage Monitoring Capability

 Remote Sense Amplifier with True Differential

Voltage Sensing

The switching frequency is programmable from 300

kHz to 1.5MHz 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.

 Smart LDO to enhance efficiency

 Vp for tracking applications and sequencing

 Vref is available externally to enable margining

 External synchronization with Smooth Clocking

 Dedicated output voltage sensing for power good

indication and overvoltage protection which

remains active even when Enable is low.

APPLICATIONS

 Enhanced Pre-Bias Start up

 Body Braking to improve transient

 Netcom Applications

 Integrated MOSFET drivers and Bootstrap diode

 Thermal Shut Down

 Embedded Telecom Systems

 Server Application

 Post Package trimmed rising edge dead-time

 Programmable Power Good Output with tracking

 Small Size 5mm x 7mm PQFN

 Distributed Point of Load Power Architectures

 Storage Applications

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

 Lead-free, Halogen-free and RoHS Compliant
