Micropower Step-up DC/DC Converter with 350mA Peak
Current Limit
General Description
The LM2703 is a micropower step-up DC/DC in a *all
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. The low
400ns off-time permits the use of tiny, low profile inductors
and capacitors to minimize footprint and cost in
space-conscious 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.
