SNVS191F – NOVEMBER 2002 – REVISED OCTOBER 2016 LM2705 Micropower Step-Up DC-DC Converter With 150-mA Peak Current Limit
1 Features 3 Description The LM2705 is a micropower step-up DC-DC
converter in a small 5-pin SOT-23 package. A
current-limited,
fixed-off-time
control
scheme
conserves operating current, which results in high
efficiency over a wide range of load conditions. The
21-V switch allows for output voltages as high as
20 V. The low 400-ns off-time 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 backlighting. The LM2705 device can drive up to 3 white
LEDs from a single Li-Ion battery. The low peakinductor current of the LM2705 makes it ideal for USB …
