RT8016

1.5MHz, 1A, High Efficiency PWM Step-Down DC/DC

Converter

General Description

Features

^ꢀ+2.5V to +5.5V Input Range

^ꢀAdjustable Output From 0.6V to V_IN

^ꢀ1A Output Current

The RT8016 is a high-efficiency Pulse-Width-Modulated

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

1A output current over a wide input voltage range from

2.5V to 5.5V, the RT8016 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.

^ꢀ95% Efficiency

^ꢀNo Schottky Diode Required

^ꢀ1.5MHz Fixed Frequency PWM Operation

^ꢀSmall 6-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 RT8016 enters Low-Dropout mode when normal PWM

cannot provide regulated output voltage by continuously

turning on the upper PMOS. The RT8016 enters shut-

down mode and consumes less than 0.1uA when EN pin

is pulled low. The RT8016 also offers a range of 1V to

3.3V with 0.1V per step or adjustable output voltage by

two external resistor.

Ordering Information

RT8016-

Package Type

QW : WDFN-6L 2x2 (W-Type)

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-6L2x2

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.

Lead Plating System

P : Pb Free

G : Green (Halogen Free and Pb Free)

Output Voltage

Default : Adjustable

10 : 1.0V

11 : 1.1V

32 : 3.2V

33 : 3.3V
