General DescriptionThe LM2705isa micropower step-up DC/DCina small
5-lead SOT-23 package.A current limited, fixed off-time
control scheme conserves operating current resultingin high
efficiency overa wide rangeof load conditions. The 21V
switch allowsfor output voltagesas highas 20V. The low
400ns off-time permits the useof tiny, low profile inductors
and capacitorsto minimize footprint and costin space-
conscious portable applications. The LM2705is idealfor
LCD panels requiring low current and high efficiencyas well white LED applicationsfor cellular phone back-lighting.
The LM2705 can driveupto3 white LEDs froma single
Li-Ion battery. The low peak inductor currentof the LM2705
makesit idealfor USB applications.
