The LM2705 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. The low 400ns offtime
permits the use of tiny, low profile inductors and capacitors
to minimize footprint and cost in space-conscious
portable applications. The LM2705 is ideal for LCD panels
requiring low current and high efficiency as well as white LED
applications for cellular phone back-lighting. The LM2705 can
drive up to 3 white LEDs from a single Li-Ion battery. The low
peak inductor current of the LM2705 makes it ideal for USB
applications.
