2 Watt Switching Power Supply

2 Watt Switching Power Supply2 Watt Switching Power Supply Schematic

In this small 2 Watt Switching Power Supply, a Schmitt activate oscillator is acclimated to drive a switching transistor that food accepted to a baby inductor. Energy is stored in the inductor while the transistor is on, and appear into the amount ambit back the transistor switches off. The achievement voltage is abased on the amount attrition and is bound by a zener diode that stops the oscillator back the voltage alcove about 14 volts. Higher or lower voltages can be acquired by adjusting the voltage affiliate that feeds the zener diode. The ability is about 80% application a aerial Q inductor.
