Overview

5V at 400mA from 2V Input
Supply Voltage As Low As 1.8V
120µA Quiescent Current
Low-Battery Detector
Low V_CESAT Switch: 310mV at 2A Typ
Uses Inexpensive Surface Mount Inductors
8-Lead SO Package

The LT1305 is a micropower step-up DC/DC converter that uses Burst Mode^™ operation. Similar to the LT1303, the LT1305 features a 2A internal low-loss switch and can deliver up to four times the output power of the LT1303.

Quiescent current is only 120µA and the Shutdown pin further reduces current to 10µA. A low-battery detector provides an open-collector output that goes low when the input voltage drops below a preset level. The LT1305 is available in an 8-pin SO, easing board space requirements.

Applications

2-Cell and 3-Cell to 5V Conversion
EL Panel Drivers
Portable Instruments
