www.ti.com SNVS152C – MAY 2001 – REVISED MARCH 2013 LM2700 600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter
Check for Samples: LM2700 FEATURES DESCRIPTION The LM2700 is a step-up DC/DC converter with a
3.6A, 80mО© internal switch and pin selectable
operating frequency. 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 quiescent current of 2.0mA
at 600kHz and 3.0mA at 1.25MHz. The LM2700 is
available in a low profile 14-lead TSSOP package or
a 14-lead WSON package. 1 2 3.6A, 0.08О©, Internal Switch
