Switching power supply experience for UC3842/3844
no vote
Application background UC3842 chip as a small power switching power supply PWM pulse width modulation chip, in the process of switching power supply maintenance, often encountered due to failure caused by the uc3842/uc3844 can not work properly, the power can not afford to start or mild vibration (measured output voltage is low), but did not have the normal work (performance 8Pin no 5V) possible reasons as follows:

Design and analysis of single ended flyback switch
no vote
Application background Power supply device is an important field of power electronics technology, in which the high frequency switching DC power supply has been widely used because of its high efficiency, small size and light weight. Switching power supply control circuit can be divided into voltage control and current control type, the former is a single closed-loop voltage control system, the system response is slow, it is difficult to achieve a higher linear adjustment rate accuracy, the latter, compared with the voltage control has incomparable advantages.
