Conv DC-DC Single-OUT Step Down 2.8V to 5.5V 16-Pin QFN

The SiP12108 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 5 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 industrialSiP12108’s CM-COT architecture delivers ultra-fast transient response with minimum output capacitance and tight ripple regulation at very light load. The part is stable with any capacitor type and no ESR network is required for loop stability. The device also incorporates a power saving scheme that significantly increases light load efficiency The SiP12108 integrates a full protection feature set, including output overvoltage protection (OVP), output under voltage protection (UVP) and thermal shutdown (OTP). The “A” version of the device, SiP12108A, does not have the UVP feature. They also incorporate UVLO for the input rail and an internal soft-start ramp
