Preliminary

RT8010B

1.5MHz, 800mA, High Efficiency PWM

Step-Down DC/DC Converter

General Description

Features

ꢀ +2.5V to +4V Input Range

The RT8010B is a high-efficiency Pulse-Width-Modulated

(PWM) step-downDC-DC converter. Capable of delivering

800mAoutput current over a wide input voltage range from

2.5V to 4V, the RT8010B is ideally suited for portable

electronic devices that are powered from 1-cell Li-ion

battery or from other power sources such as cellular

phones, PDAs and hand-held devices.

ꢀ Output Voltage (Adjustable Output From 0.6V to V_IN)

ꢀ 800mA Output Current

ꢀ 95% Efficiency

ꢀ No Schottky Diode Required

ꢀ 1.5MHz Fixed-Frequency PWM Operation

ꢀ Small 8-Lead WDFN Package

ꢀ RoHS Compliant and 100% Lead (Pb)-Free

Two operating modes are available including PWM/Low-

Dropout autoswitch and shut-down modes. The 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

ꢀ Personal InformationAppliances

ꢀ Wireless and DSL Modems

ꢀ MP3 Players

The RT8010B enters Low-Dropout mode when normal

PWM can not provide regulated output voltage by

continuously turning on the upper PMOS. The RT8010B

enters shut-down mode and consumes less than 0.1μA

when EN pin is pulled low.

Pin Configurations

(TOP VIEW)

The switching ripple is easily smoothed-out by small

package filtering elements due to a fixed operating

frequency of 1.5MHz. This along with small WDFN-8L2x2

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.
