Final Electrical Specifications

LT1308

Single Cell High Current

Micropower 600kHz

Boost DC/DC Converter

January 1998

DESCRIPTION

FEATURES

The LT^®1308 is a micropower, fixed frequency boost

DC/DC converter that operates from an input voltage as

low as 1V. Capable of delivering 5V at load current of 1A

from a single Li-Ion cell, the LT1308 also features power

savingBurstModeoperationatlightloads. Highefficiency

is maintained over a broad 1mA to 1A load range.

■

5V at 1A from a Single Li-Ion Cell

■

3.3V at 300mA from a Single NiCd Cell

■

Low Quiescent Current: 100µA

■

Operates with V_INas Low as 1V

■

Fixed Frequency Operation: 600kHz

■

Current Mode PWM Delivers Low Output Ripple

■

Guaranteed Start-Up into Full Load

The device contains a low-battery detector with a 200mV

reference and shuts down to less than 5µA quiescent

current. No-load quiescent current is 100µA and the

internal NPN power switch handles a 2A current with a

voltage drop of just 300mV.

■

Low Shutdown Current: 3µA

■

Low-Battery Comparator

Automatic Burst Mode^TMOperation at Light Load

■

Low V_CESAT

^SwitU^{ch: 300mV at 2A}

High frequency 600kHz switching allows the use of small,

surface mount components. The LT1308’s current mode

architecture provides fast response to load and line varia-

tions. The device is available in an 8-lead SO package.

APPLICATIONS

■

GSM Terminals

Digital Cameras

Answer-Back Pagers

Cordless Telephones

DECT Phones

GPS Receivers
