Build a circuit to boost the voltage of a DC power source using a MAX756 IC Chip
A DC voltage booster, DC voltage multiplier, or DC-DC Step-Up Converter is a very useful tool which enables a low source DC voltage to be boosted (stepped up) to a higher output DC voltage which is more useful.
For example, ultrabright LEDs need a 2.5-3.5 Volts to light: even two AA rechargeable batteries in series (1.2 + 1.2 = 2.4V) would not provide sufficient voltage to light up LEDs. Using a voltage boost circuit an LED can be powered by just one AA battery or any other power source – sometimes down 0.7 Volts!
This circuit can be used with low voltage solar panels to make a small battery charger or to power a 5 Volt device directly. It is also particularly good for getting useable voltages from small DIY stepper motor wind turbines – again to charge batteries or light LEDs.
