I am working on a power supply project recently. It requires an input voltage of 60V, an output of 15V, a disable function, and efficiency requirements. Therefore, a DCDC step-down switching power sup...
I have asked a question before, and I want to talk about how to amplify a 2MHz sinusoidal signal to 300v. Thank you for your answers.
Now I have made a low frequency transformer, the frequency is 200k...
The name of the watchdog is quite interesting. Its function is to bite the owner when he is distracted to wake him up. In practical terms, when the MCU enters an infinite loop somewhere during operati...
Please help me, U1A and U1B are two voltage followers, U1C subtracts the two voltages, but why when I measure the potential of the two points in the figure, the voltage value keeps changing and is uns...
