  • RE: BQ25756: the charge and discharge current during constant current mode

    meme wang 说： Could you clarify which pin is used to set this certain current value? The ICHG pin is used to set pre-charge, ICHG, and the termination current. For a capacitor, you'll want to set EN_TERM=0 and EN_PRECHG=0 to disable termination and precharge…

  • RE: LM5045: 100Wdcdc全桥带载输出掉电压

    您好， 是的，相位裕度与电源变换器的环路控制理论相关。 大部分关于环路响应的分析都是在频域中进行的——您可以参考以下应用说明： 6445.switchingpower_compensation.pdf

  • RE: LM5116: 逐周期和短路保护的时序和具体计算的方法是怎样的.

    已解决
    HI 见datasheet描述： Since the ramp amplitude is proportional to VIN - VOUT, if VOUT is shorted, there is an immediate reduction in duty cycle. To further protect the external switches during prolonged current limit conditions, an internal counter counts…

  • why can't a mosfet be directly driven by a microcontroller?

    First, microcontroller I/O ports have limited load capacity, typically allowing currents around 10-20 mA. Therefore, they are generally not used to drive loads directly. Let's briefly compare the differences in driving BJTs and MOSFETs. Bipolar…
