DC Step Up Voltage Converter Description.

A simple DC to DC step up  voltage converter using LM2700 is shown here. LM2700 is a step up switching converter that has a 3.6A, 80 M ohm internal switch. It can be operated at 600 kHz or 1.25MHz switching frequency.
In the circuit LM2700 is wired in order to produce 8V DC output from a 3V input at a switching frequency of 600MHz. Resistor network consisting of R2 and R3 sets the output voltage. Capacitor C1 and C2 are meant for input voltage filter for reducing ripple and noise. FSCLT pin (pin13) is connected to ground in order to run the IC at 600KHz switching frequency. Connecting this pin to Vin will make the IC run at 1.25MHz.
