Datasheet
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-powered devices where lowest
quiescent current and high efficiency are essential.
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
