The price of TPS54340 has risen from 3.5 to 15 yuan. Now 431 is used as the reference and loop, 5 BJTs are used for PWM+DRV, and NMOS is promoted. The replacement cost is 1.2 yuan. The efficiency is e
Metal halide high-intensity discharge lamps, commonly known as HID, can be applied to many fields, especially in automotive lighting, which can effectively reduce accidents and benefit mankind. Existi
For bidirectional DC converters, some tubes have large voltage ringing spikes when boosting, but the voltage is much improved when stepping down, and the opposite is true for some tubes. In addition t
I would like to ask how to calculate the resistance value and choose the model of the resistor? I only know that this should use the RC discharge curve to calculate the resistance value and power? I d
