Uc3842 Application Circuit Diagram. Inductor used in above circuit diagram should be made using ferrite core and select proper wire to make inductor according to current rating of led driver. You don t have a knowledge about pwm controller ics.
Functional description a block diagram of the uc3842 appears in figure 4. Applications off line switched mode power supplies dc to dc converters uc3842 block diagram note. The 6v hysteresis prevents vcc oscillations during power sequencing.
Don t worry i will write a complete article on uc3842 pwm controller in coming days.
