Voltage converter with regulated switching frequency and minimum on-time coverage

Systems and methods for a voltage converter are described. The controller may include determining a pulse width modulation (PWM) on duration for operating the voltage regulator. The controller may determine a switching frequency for operating the voltage regulator. The controller may determine whether the PWM ON duration is greater than the ON time reference or less than the ON time reference. In response to determining that the PWM on-duration is less than the on-time reference, the controller may increase a voltage window of a PWM signal for operating the voltage regulator. In response to determining that the PWM ON duration is greater than the ON time reference, the controller may execute a frequency locked loop (FLL) to adjust the switching frequency. 描述了用于电压转换器的系统和方法。控制器可以包括确定用于操作电压调节器的脉宽调制(PWM)接通持续时间。控制器可以确定用于操作电压调节器的开关频率。控制器可以确定PWM接通持续时间是大于接通时间参考或是小于接通时间参考。响应于确定PWM接通持续时间小于接通时间参考，控制器可以增大用于操作电压调节器的PWM信号的电压窗口。响应于确定PWM接通持续时间大于接通时间参考，控制器可以执行频率锁定环(FLL)以调节开关频率。
