Datasheet
1 General Description
The AS1326A/AS1326B are high-efficiency, high cur-
rent, DC-DC step-up converters specifically designed for
battery-powered wireless applications. Low quiescent
supply current (65μA), high operating frequency (1MHz),
and minimal external component requirements make
these devices perfect for small hand-held applications.
Table 1. Standard Products
Both devices use synchronous-rectified pulse-width
modulation (PWM) boost technology to generate 2.5 to
5.0V outputs from a wide range of inputs, such as 1 to 3
alkaline/NiCd/NiMH cells or a single lithium-ion (Li+)
cell. Automatic powersave operation significantly
improves efficiency at light-loads.
Continuous switching mode is available for applications
requiring constant-frequency operation at all load cur-
rents. PWM operation can also be synchronized to an
external clock to protect sensitive frequency bands in
communications equipment.
Analog soft-start and adjustable current limit permit opti-
mization of rush in current and external component size.
The AS1326A/AS1326B are available in a 10-pin TDFN
(3.0mm x 3.0mm) package.
