DESCRIPTION
The LM2700 is a step-up DC/DC converter with a 3.6A, 80mΩ internal switch and pin selectable operating frequency. With the ability to produce 500m A 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 600k Hz and 1.25MHz allowing for easy filtering and low noise. An external pensation pin gives the user flexibility in setting frequency pensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The LM2700 features continuous switching at light loads and...
