LM2704 Micropower Step-up DC/DC Converter with 550mA Peak Current Limit

Check for Samples: LM2704

FEATURES

DESCRIPTION

The LM2704 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 off-time permits the

use of tiny, low profile inductors and capacitors to

minimize footprint and cost in space-conscious

portable applications. The LM2704 is ideal for LCD

panels requiring low current and high efficiency as

well as white LED applications for cellular phone

back-lighting. The LM2704 can drive up to 8 white

LEDs from a single Li-Ion battery.
