6v to 12v converter circuits

Posted on Feb 6, 2014

6V to 12V DC converter circuits that can be used to convert a small voltage of about 6 volts to a higher voltage of 12 volts but ofcourse with a lower current rating. This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V car. The circuit is simple, about

75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages. The cost of building the 6volts to 12 volts converter should be low enough to justify constructing it instead of modifying the entire equipment setup to work directly with a 6 volts power supply. The two principles of simplicity and functions properly without the need of the transformer. This is a Simple Switcher step-up voltage regulator made by National Semiconductor, (part number LM2577-ADJ). Together with a few extra components, a heat sink and some wiring, it is possible to generate over 1A from the battery of an Austin. The output connector is taken from a car charger extension lead, so that a phone or a sat-nav just plugs straight in. This 6V to 12V dc-dc boost converter can drive a load in 12V about 3A current. The 555 timer IC is operated in astable mode, generates about 29Khz frequency of about 54% duty cycle drives the input of TIP41C transistor. 1000uF capacitor smoothens the output voltage of the dc-dc converter. LED and 1. 5Kohm resistor serves as indicator and load for output stability when no load is connected. You can add a 12V zener diode (1N5242B)across output to ground for further output stability.
