AC to DC converter circuit diagram
MC34161 includes a reference power supply which delivers 2.54V at pin 1. The signal level applied at pin 2 is internally compared with a 1.27V voltage.
D5 zener diode, togheter with R1 and C4 provide IC’s required 12V voltage. Capacitor’s voltage of C2 and C3 must be greater than 250V.
Attention: this ac to dc converter contains very high voltages that are deadly and you must be very careful!
