Abstract: A digital device generates a fixed duty cycle signal with an internal oscillator after a Power-On-Reset (POR). This fixed duty cycle signal is output on a signal pin that normally is used for a PWM control signal. The fixed duty cycle signal is used to stimulate the voltage generation circuits so as to power up the digital device for initialization thereof. Once the digital device has powered-up and initialized, the digital device switches over to normal operation for control of the power system.

Abstract translation: 数字设备在上电复位（POR）之后，通过内部振荡器产生固定占空比信号。 该固定占空比信号在通常用于PWM控制信号的信号引脚上输出。 固定占空比信号用于激励电压产生电路，以便为数字设备供电以进行初始化。 一旦数字设备通电并初始化，数字设备将切换到正常操作，以控制电源系统。
