60 Watt Switching Power Supply

60 W Switching power supplyThe scheme is a classical flyback power supply for PWM UC3842. Since the scheme’s base power supply output parameters can be easily converted to the necessary. As an example, for the consideration of selected Power supply for  Notebook Power 20V 3A. If necessary, you can get some voltage related or independent.


Output Power 60W depends mainly on the parameters of the power transformer. If they change can be obtained an output power up to 100W in the standard size of the core. Operating frequency is selected 29Khz block can be rebuilt and capacitor C1. The power supply is designed for unaltered or little-changing workload, hence the lack of stabilization of output voltage, although it is stable with fluctuations Network 190 … 240volt. Efficiency Unit – 87%. No external control, but can be entered using optocouplers or relays.
