LM2700
600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter
General Description
The LM2700 is a step-up DC/DC converter with a 3.6A,
80m
internal switch and pin selectable operating fre-
quency. With the ability to produce 500mA at 8V from a
single Lithium Ion battery, the LM2700 is an ideal part for
biasing LCD displays. The LM2700 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 LM2700 features continuous
switching at light loads and operates with a switching quies-
cent current of 2.0mAat 600kHz and 3.0mAat 1.25MHz. The
LM2700 is available in a low profile 14-lead TSSOP package
or a 14-lead LLP package.
