Minimum Time(最小时间)— 非同步停止输入有效时禁用pwm输出,在经过最小时间后才会重新启用。 最小非同步停止输入时间(软件) 最小非同步停止输入时间参数用于定义当 Kill Mode参数设置为Minimum Time(最小时间)时,所需有效非同步停止输入信号的最小长度。 非同步停止输入的最小时间是使用时钟计数1到255范围内...
Optimizing light control with PWM requires minimum slew-up and slew-down delays not only for best contrast ratio, but to minimize the time that the LED spends between zero and the target level (where the dominant wavelength and CCT are not guaranteed). A standard switching regulator will have ...

Whereas in the original system, the maximum ripple currents occur at a duty cycle of 50% and the minimum ripple currents occur at the minimum duty cycle, the improved version shows a maximum ripple equal to the minimum of the standard version. The trick is to generate the highest frequency ...
Simulation results show that the minimum overshoot absolute value of 1.23% and the maximum power factor of 0.986 14 can be obtained by Pareto front optimal design space respectively. However, these two objectives cannot be optimized at the same time, and the pursuit of higher power factor will ...
Enter the minimum PWM value (0-255) at which the fan STOPS spinning (press t to test) (100): t Now we decrease the PWM value to figure out the lowest usable value. (每个人的风扇型号不一样,这里可能会有差异,我的是12cm猫扇)

FAN6754 integrates a frequency-hopping function internally to reduce EMI emission of a power supply with minimum line filters. Built-in synchronized slope compensation is accomplished by, proprietary internal compensation for constant output power limit over universal AC input range. Also, the gate outp...
