    • Circuits and methods to detect a threshold for entering and leaving a discontinuous current mode of a buck converter have been disclosed. A buck converter is switched to continuous mode if the filtered battery current has reached a defined threshold current Ithccm. In order to expedite the transition from DCM mode to CCM mode the time delay between two or more pulses of a current through an inductor is monitored and the buck converter is switched to CCM mode if this time delay is smaller than a defined threshold.
    • 已经公开了用于检测用于进入和离开降压转换器的不连续电流模式的阈值的电路和方法。 如果滤波后的电池电流达到规定的阈值电流Ithccm,则降压转换器切换到连续模式。 为了加速从DCM模式转换到CCM模式,监视通过电感器的电流的两个或多个脉冲之间的时间延迟,并且如果该时间延迟小于定义的阈值,则降压转换器被切换到CCM模式。
