Components and its usage:

IC Switcher/regulator LM2577T-ADJ (Texas Instrument)
R1 and R2 Voltage devider for monitoring output voltage 20Kohms pot. (Bourns)
Cin Decoupling 0.1?F, 63V MKS condensator (WIMA)
L Use a good quality coil! 160?H toro?d (2.5A, 70mohms, nickel-iron core)
D Current higher than output current! FR603 60V reverse breakdown, 3A Schottky-diode
Rc and Cc Pole-zero compensation network 2200ohms, 5% and 1?F, 63V elco (Philips)
Cout Get a low ESR type! 2200?F, 16V elco (Telecon)


6V to 12V DC to DC voltage converter circuit works:

When the switch is closed an extra current flows through the inductance and stores energy there. The capacitor supplies the load with current during this time.

After the switch closes the capacitor is charged by the energy stored in the inductance and an extra current starts flowing through the load, causing the output voltage to rise (energy is supplied directly from the input source also as long as the diode is forward biased). During this time, the system behaves like a RLC-circuit, so, after a while, the current decreases. The switch is then closed again and the cycle repeats. One could say that charge is pumped from input to output, increasing the output voltage up to the point where there is an equilibrium between the discharging of the capacitor while the switch is closed and the charging by the inductor while the switch is open.
