Uc3842 Smps Circuit Diagram. Input ac voltage range. Linear topology would be unusable for this power 2400w 2 4 kilowatts so i chose a switching topology of a two switch forward half controlled bridge.
Hello i would like to design a flyback smps based on uc3842 with following specs. One or more uc3842 oscillators can be synchroni zed to an external clock as shown in figure 8. 120watt this smps is meant to be used to power led lighting strips that operate at 12volt.
Either raise pin 3 above 1v or pull pin 1 below a voltage two diode drops above ground.
Noise immunity is enhanced if the free running oscillator frequency f 1 tc td is programmed to be 20 less than the clock frequency.

I got this project from a member and have redrawn the diagram for easy fixing.
