General Description

The AS1326A/AS1326B are high-efficiency, high current, 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.
