Power supply design that achieves low leakage current while maintaining EMI performance[ Print ][ Return ]在AC-DC开关电源中,漏电流最主要的来源是Y类电容。通过使用变压器屏蔽绕组或在输入级加入一个扼流圈,可以显著地降低Y电容的数值或在某些场合去除它,从而降低漏电流并且仍满足有一定裕量的传导...
Many battery-powered applications require a buck converter to operate at 100% duty cycle, where V IN is close to V OUT , to extend battery life when the battery voltage reaches its minimum value.
For ...
High-Definition Multimedia Interface (HDMI) has become a widely used interface standard for digital televisions and consumer electronics products, bringing high-quality experience to home entertainmen...
As shown in the figure below, A and B are inputs, and C is output. After B generates a high level, C outputs a high level at the rising edge of A. C outputs a low level at the rising edge of B. If B m...
