LM3206

650mA Miniature, Step-Down DC-DC Converter for

Portable Applications

General Description

Features

The LM3206 is a DC-DC converter optimized for powering

portable applications from a single Lithium-Ion cell, however

they may be used in many other applications. It steps down

an input voltage from 3.25V to 5.5V to a fixed output voltage

of 3.09V.

2 MHz (typ.) PWM Switching Frequency

■

Operates from a single Li-Ion cell

Fixed Output Voltage (3.09V)

650mA Maximum load capability

High Efficiency (96% Typ at 3.6V_IN, 3.09V_OUTat 400mA)

from internal synchronous rectification

8-pin micro SMD Package

Current Overload Protection

Thermal Overload Protection

Soft Start function

■

The LM3206 offers superior performance for mobile phones

and other applications requiring low dropout voltage. Fixed-

frequency PWM operation minimizes RF interference. The

Shutdown function turns the device off and reduces battery

consumption to 0.01 µA (typ.).

■

The LM3206 is available in an 8-pin lead free micro SMD

package. A high switching frequency (2 MHz) allows use of

tiny surface-mount components. Only three small external

surface-mount components, an inductor and two ceramic ca-

pacitors are required.

Low Dropout Voltage (140 mΩ Typ PFET)

Applications

Cellular Phones

■

Hand-Held Radios

RF PC Cards

Battery Powered RF Devices

RFIC Chipsets
