RT8079A

2.95V to 6V Input, 3A Output, 2MHz, Synchronous

Step-Down Converter

General Description

Features

 Integrated 45mΩ MOSFETs

 Input Range : 2.95V to 6V

The RT8079Ais a high efficiency step-down converter and

capable of delivering 3A output current over a wide input

voltage range from 2.95V to 6V.

 Adjustable PWM Frequency : 300kHz to 2MHz

 Output Current : 3A

The RT8079Aprovides accurate regulation for a variety of

loads with 3% accuracy. For reducing inductor size, it

provides up to 2MHz switching frequency. The efficiency

is maximized through the integrated 45mΩ MOSFETs

and 550μA typical supply current.

 95% Efficiency

 Adjustable Soft-Start

 Power Good Indicator

 Enable Control

 Under Voltage Lockout

 Current Limit

Under voltage lockout voltage of the RT8079A is 2.7V,

and it also provides external setting by a resistor network

on the enable pin.

 Thermal Shutdown

 16-Lead WQFN Package

 RoHS Compliant and Halogen Free

The RT8079A provides protections such as inductor

current limit under voltage lockout and thermal shutdown.

The over temperature threshold is 145°C.

Applications

 Low-Voltage, High-Density Power Systems

The RT8079Ais available in WQFN-16L 3x3 package.

 Distributed Power Systems

 Point-of-Load Conversions
