Typical application diagram of KJ004-wiring diagram and waveform diagram

Its typical application circuit is shown in Figure 12-3a, and the waveforms of each pin are shown in Figure 12-3b (R refers to pin 8, and
the remainder are the same). Its working principle. The slope of the sawtooth waveform is determined by the external resistor R. ,
the charging current flowing out of RR and the integrating capacitance C. The value of , for different phase shift control voltage n,
just change the weight resistor R. ,R. By adjusting the corresponding offset voltage vr and adjusting
the sawtooth wave slope potentiometer RP, the phase shift within the entire phase shift range can be obtained at different phase shift control voltages .
The KJ004 trigger circuit has positive polarity, that is, as the phase shift voltage increases
, the conduction angle increases. R in the picture. and <,. By forming a differential circuit and changing the values ​​of R and C:,
different pulse width outputs can be obtained, along with the input synchronization voltage and the series
resistor between pin 8 . Depending on the value, the synchronization voltage value can take any value.
