RT8015D

3A, 2MHz, Synchronous Step-Down Converter

General Description

Features

^zHigh Efficiency : Up to 95%

The RT8015D is a high efficiency synchronous, step-down

DC/DC converter. Its input voltage range is from 2.6V to

5.5V and provides an adjustable regulated output voltage

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

^zLow R_DS(ON)Internal Switches : 110mΩ

^zProgrammable Frequency : 300kHz to 2MHz

^zNo Schottky Diode Required

^z0.8V Reference Allows for Low Output Voltage

^zForced Continuous Mode Operation

^zLow Dropout Operation : 100% Duty Cycle

^zPower Good Output Voltage Indicator

^zRoHS Compliant and Halogen Free

The internal synchronous low on-resistance power

switches increase efficiency and eliminate the need for

an external Schottky diode. The switching frequency is

set by an external resistor. The 100% duty cycle provides

low dropout operation extending battery life in portable

systems. Current mode operation with external

compensation allows the transient response to be

optimized over a wide range of loads and output capacitors.

Applications

z Portable Instruments

z Battery-Powered Equipment

z Notebook Computers

z Distributed Power Systems

z IP Phones

The RT8015D is operated in forced continuous PWM Mode

which minimizes ripple voltage and reduces the noise and

RF interference.

The 100% duty cycle in Low Dropout Operation further

maximize battery life.

z Digital Cameras

Pin Configurations

The RT8015Dis available in the WDFN-10L 3x3 package.
