3 to 12 Volts Converter with LM2700

This is very simple electronic circuit diagram for 3 to 12 volts converter, this circuit simple and high efficiency step-up dc dc converter circuit that require few external components can be designed using the LM2700 step-up DC/DC converter with a 3.6A, 80mohms internal switch and pin selectable operating frequency.

3 to 12 Volts Converter Circuit Diagram:

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.

This circuit can be used for handheld devices and some other portable applications. This step-up DC DC converter will provide a 12 volts DC output voltage from an input voltage range between 2.5 to 4.2volts.
