I am a little confused about the calculation of constant voltage BUCK inductor. The input voltage range is required to be 176-265Vac, the output is 9V/1A, the efficiency is 91%, and the core is EE10.
The hardware guy in our company drew a board and wanted to modify it by adding a wire, but the guy resigned.My boss asked me to do it. I added a wire directly to the PCB without going through the sche
(1) The power line is an important way for EMI to enter and exit the circuit. Through the power line, external interference can be transmitted to the internal circuit and affect the RF circuit indicat
Large-capacity memory (such as DRAM) has limited access speed, which is generally much slower than the CPU clock speed; small-capacity memory (such as SRAM) can provide fast access speed. Therefore, m
This is a DS waveform of a flyback switching power supply. How is the peak voltage in the T1 area generated? How are the oscillations in the T2 and T4 areas generated? And why is the voltage in the T3
