图1SiP12107内部结构图

The SiP12107 is a high frequency current-mode constant on-time (CM-COT) synchronous buck regulator with integrated high-side and low-side power MOSFETs. Its power stage is capable of supplying 3 A continuous current at 4 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 2.8 V to 5.5 V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial.
