LM2703 - Micropower Step-Up DC/DC Converter

General Description

The LM2703 is a micropower step-up DC/DC in a small 5-lead SOT-23 package.

A current limited, fixed off-time control scheme conserves operating current resulting in high efficiency over a wide range of load conditions.

The 22V switch allows for output voltages as high as 21V.
