IR3853MPbF

HIGHLY EFFICIENT

SupIRBuck

INTEGRATED 4A, SYNCHRONOUS BUCK REGULATOR

Features

Description

•

Greater than 95% Maximum Efficiency

Wide Input Voltage Range 1.5V to 21V

Wide Output Voltage Range 0.7V to 0.9*Vin

Continuous 4A Load Capability

The IR3853 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

Integrated Bootstrap-diode

IR3853

space-efficient solution, providing

High Bandwidth E/A for excellent transient

performance

accurate power delivery for low output voltage

applications.

•

Programmable Switching Frequency up to 1.5MHz

Programmable Over Current Protection

Over Voltage Protection

IR3853 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.

Dedicated input for output voltage monitoring

Programmable PGood output

Hiccup Current Limit

The switching frequency is programmable from

250kHz to 1.5MHz for an optimum solution.

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

Programmable Soft-Start

Enable Input with Voltage Monitoring Capability

Enhanced Pre-Bias Start-up

It also features important protection functions,

such as Pre-Bias startup, hiccup current limit,

over-voltage, and thermal shutdown to give

required system level security in the event of fault

conditions.
