请问一下DCS控制（Direct Control with Seamless transition into power-save mode）的资料

Hi
没有找到特别详细的控制描述文档，只能参考一些datasheet说明：
DCS-Control™ (Direct Control with Seamless
transition into Power Save Mode). This is an advanced regulation topology that combines the advantages of
hysteretic and voltage mode control.
The DCS-Control™ topology operates in PWM (Pulse Width Modulation) mode for medium to heavy load
conditions and in Power Save Mode at light load currents. In PWM, the converter operates with its nominal
switching frequency of 1.4 MHz having a controlled frequency variation over the input voltage range. As the load
current decreases, the converter enters Power Save Mode, reducing the switching frequency and minimizing the
IC's quiescent current to achieve high efficiency over the entire load current range.
