AS1323

1.6µA Quiescent Current, Single Cell, DC-DC Step-up Converter

1 General Description

2 Key Features

The AS1323 high-efficiency step-up DC-DC converter

was designed specifically for single-cell, battery-pow-

ered devices where lowest quiescent current and high

efficiency are essential.

ꢀ

1.6µA Quiescent Current

Input Voltage Range: 0.75 to 2V

Up to 100mA Output Current

Fixed Output Voltages: 2.7, 3.0 and 3.3V

Shutdown Current: 0.1µA

The compact device is available in three fixed-voltage

variations and is perfect for a wide variety of applications

where extremely-low quiescent currents and very-small

form factors are critical.

The devices are available as the standard products

shown in Table 1. See also Ordering Information on

page 13.

Output Voltage Accuracy: ±3%

Efficiency: Up to 85%

Guaranteed 0.95V Start-Up Voltage

TSOT23-5 Package

Integrated boot circuitry ensures start-up even with very-

high load currents.

The true output disconnect feature completely discon-

nects the output from the battery during shutdown.

The device is available in a TSOT23-5 pin package.

3 Applications

The devices are ideal for single-cell portable devices

including mobile phones, MP3 players, PDAs, remote

controls, personal medical devices, wireless transmitters

and receivers, and any other battery-operated, portable

device.
