Shi Min, invented the floating gate transistor of non-volatile memory, which promoted the development of mobile phones. The PPT mentioned the challenges of microelectronics technology: wafer: 18 inche...
As shown
The purpose of the circuit is to use the triangle wave input at the same phase end and the variable DC input at the inverting end to generate a PWM wave with adjustable duty cycle through the...
[size=5]It is connected to a 12V lead-acid battery, so it requires higher efficiency and small size, so heat dissipation is a problem. Don't let it be too hot. The main thing is to be stable and relia...
1. Single-sided pad: Do not use filler blocks as pads for surface mount components. Single-sided pads should be used. Normally, single-sided pads are not drilled, so the aperture should be set to 0. [...
