RT8020

Dual High-Efficiency PWM Step-Down DC/DC Converter

General Description

Features

^ꢀ2.5V to 5.5V Input Range

The RT8020 is a dual high-efficiency Pulse-Width-

Modulated (PWM) step-down DC/DC converter. It is

capable of delivering 1A output current over a wide input

voltage range from 2.5V to 5.5V, the RT8020 is ideally

suited for portable electronic devices that are powered

from 1-cell Li-ion battery or from other power sources within

the range such as cellular phones, PDAs and other hand-

held devices.

^ꢀAdjustable Output From 0.6V to V_IN

^ꢀ1.2V, 1.3V, 1.8V, 2.5V and 3.3V Fixed/ Adjustable

Output Voltage

^ꢀ1A Output Current

^ꢀ95% Efficiency

^ꢀNo Schottky Diode Required

^ꢀ50uA Quiescent Current per Channel

^ꢀ1.5MHz Fixed Frequency PWM Operation

^ꢀSmall 12-Lead WDFN Package

^ꢀRoHS Compliant and 100% Lead (Pb)-Free

Two operational modes are available : PWM/Low-Dropout

auto-switch and shutdown modes. Internal synchronous

rectifier with low R_DS(ON)dramatically reduces conduction

loss at PWM mode. No external Schottky diode is

required in practical application.

Applications

ꢀ Mobile Phones

The RT8020 enters Low-Dropout mode when normal PWM

cannot provide regulated output voltage by continuously

turning on the upper PMOS. The RT8020 enter shutdown

mode and consumes less than 0.1μAwhen ENpin is pulled

low.

ꢀ Personal InformationAppliances

ꢀ Wireless and DSL Modems

ꢀ MP3 Players

ꢀ Portable Instruments

The switching ripple is easily smoothed-out by small

package filtering elements due to a fixed operation

frequency of 1.5MHz. This along with small

WDFN-12L 3x3 package provides small PCB area

application. Other features include soft start, lower internal

reference voltage with 2% accuracy, over temperature

protection, and over current protection.
