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. The low
400ns off-time permits the use of tiny, low profile inductors
and capacitors to minimize footprint and cost in spaceconscious
portable applications. The LM2703 is ideal for
LCD panels requiring low current and high efficiency as well
as white LED applications for cellular phone back-lighting.
The LM2703 can drive up to 4 white LEDs from a single
Li-Ion battery.
