DESCRIPTION

The LM2700Q is a step-up DC/DC converter with a

3.6A, 80mΩ internal switch and pin selectable

operating frequency. With the ability to produce

500mA at 8V from a single Lithium Ion battery, the

LM2700Q is an ideal part for biasing LCD displays.

The LM2700Q can be operated at switching frequencies of 600kHz and 1.25MHz allowing for

easy filtering and low noise. An external

compensation pin gives the user flexibility in setting

frequency compensation, which makes possible the

use of small, low ESR ceramic capacitors at the output. The LM2700Q features continuous switching

at light loads and operates with a switching quiescent

current of 2.0mA at 600kHz and 3.0mA at 1.25MHz.

The LM2700Q is available in a low profile 14-lead

TSSOP package or a 14-lead WSON package.
