Description
Circuit diagram like in Figure 1. is Circuit Diagram DC Boost Converter circuit 3.3-5v to 12V-13.8V using KA34063 IC. According Eleccircuits site that publish this circuit describe that this is DC boost converter circuit that can use 3.3V to 5V power supply source into DC 12V-13.8V output max current 100mA. It is switching circuit better than old circuit.
You can increase low voltage battery to high voltage load as you need with high efficiency. The circuit will show in Figure 5, the operation start with when we apply the power supply to the circuit. The IC1 will acts as the step up voltage converter. The voltage will increased to pin 1 of IC1-KA34063 through diode D1 to OUT point. We can adjust the output voltage by adjusting at VR1.
