The SiP12116 is a high frequency current-mode constant-on-time (CM-COT) synchronous buck regulator with integrated high-side and low-side power MOSFETs. This regulator provides an adjustable output voltage which in standard setup can output 5 V down to 0.6 V to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial. The CM-COT architecture delivers ultra-fast transient response with minimum output capacitance and tight ripple regulation at very light load. The parts are stable with any capacitor type and no ESR network is required for loop stability. The regulator integrates a full protection feature set, it also has UVLO for the input rail and an internal soft-start. The SiP12116 is available in lead (Pb)-free power enhanced 3 mm x 3 mm DFN-10 package.
