LTC3400-1

600mA, 1.2MHz Micropower

Synchronous Boost Converter

in ThinSOT

FEATURES

DESCRIPTIO

■

Up to 92% Efficiency

The LTC^®3400-1 is a synchronous, fixed frequency, step-

up DC/DC converter delivering high efficiency in a 6-lead

ThinSOT™ package. Capable of supplying 3.3V at 100mA

from a single AA cell input, the device contains an internal

NMOS switch and PMOS synchronous rectifier.

Generates 3.3V at 100mA from a Single AA Cell

■

Low Start-Up Voltage: 0.85V

■

■

Internal Synchronous Rectifier

■

2.5V to 5V Output Range

A switching frequency of 1.2MHz minimizes solution

footprint by allowing the use of tiny, low profile inductors

and ceramic capacitors. The current mode PWM design is

internally compensated, reducing external parts count.

The LTC3400-1 features automatic shifting to power sav-

used for backup power. The LTC3400-1 features low

shutdown current of under 1µA.
