RT8063

3A, 2MHz, Synchronous Step-Down Converter

General Description

Features

^zHigh Efficiency : Up to 95%

The RT8063 is a high efficiency synchronous, step-down

DC/DC converter. Its input voltage range is from 2.7V to

5.5V and provides an adjustable regulated output voltage

from 0.8V to 5V while delivering up to 3A of output current.

z Adjustable Frequency : 200kHz to 2MHz

^zNo Schottky Diode Required

^z0.8V Reference Allows Low Output Voltage

^zLow Dropout Operation : 100% Duty Cycle

^zEnable Function

The internal synchronous low on resistance power

switches increase efficiency and eliminate the need for

an external Schottky diode. The default switching

frequency is set at 2MHz, if the RT pin is left open. It can

also be varied from 200kHz to 2MHz by adding an external

resistor. Current mode operation with external

compensation allows the transient response to be

optimized over a wide range of loads and output capacitors.

^zInternal Soft-Start

^zRoHS Compliant and Halogen Free

Applications

z LCDTV and Monitor

z Notebook Computers

z Distributed Power Systems

z IP Phones
