Additional Information
This circuit will
boost (increase) an input voltage of 0.7 to 5 Volts DC to an output voltage of up to
200mA of 5 Volts DC.
The circuit is built around the
MAX756 integrated circuit (pictured above). Further details are available in our article
DC Voltage Multiplier Circuit Plans.
This circuit can be used in many applications - for example, powering
LED bulbs from just one AA battery or for using up the energy left in disposable batteries when they are
flat.
The circuit can be used in any application in which 5 Volts is required at a current of less than 200mA. The input electricity can come from one or two
rechargeable AA batteries, disposable batteries (even when they are too
flat to be used normally), or from a small
solar panel
3.3V Output Voltage - Alternative Configuration
The
MAX756 can also be configured to provide up to
300mA of 3.3 Volts DC from input voltages of 0.7-3.3 Volts. If you are interested in purchasing such a circuit then please
contact us directly and we will discuss your exact requirements. Pricing is exactly the same as for the 5 Volt output version.
NEW If you have a 5-12 VDC voltage to boost (up to 200mA at 7-24V DC) click here to find out more about our new
Adjustable Step Up Voltage Regulator.
