LM2704 - Micropower Step-up DC/DC Converter
The LM2704 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 21V switch allows for output voltages as high as 20V.
