12+ Uc3842 Circuit Diagram. Normally whenever the power fet shorted, chances are very high i personally had tested some of the defective uc3842 ic where it tested good with meter but failed when on load (in circuit). Either method caused the output of pwm comparator to be high(refer to block diagram).the pwm latch is reset dominant so that the output will remain low until the next clock cycle after the.
Uc3842 ic can be easily found in most of the electronic equipment switching power supply. Normally whenever the power fet shorted, chances are very high i personally had tested some of the defective uc3842 ic where it tested good with meter but failed when on load (in circuit). This technique results in improved line regulation, enhanced load response characteristics, and a simpler.
