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.
