UC3846 uses sampling resistor to detect the primary center tap current to control the duty cycle. Now it is open loop. After the feedback input voltage is given, when the input voltage rises, the duty
Haha, although this is a weak question, I'd like to share with you guys. Generally, when a car passes by, the alarm will sound. A slight vibration will sound the alarm, not to mention a thunderstorm.
I would like to ask a question: I use C8051F361 microcontroller, and use P14 and P15 pins to measure the input signal frequency. I give P15 a 1.25 reference voltage. P14 pin is the input signal. But t
