THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 5 V, 3 A Current-Mode Constant On-Time Synchronous Buck Regulator DESCRIPTION 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. SiP12107’s CM-COT architecture delivers ultra-fast transient response with minimum output capacitance and tight ripple regulation at very light load. No ESR or external ESR network is required for loop stability purpose. The device also incorporates a power saving scheme that significantly increases light load efficiency. The regulator integrates a full protection feature set, including output overvoltage protection (OVP), output under voltage protection (UVP) and thermal shutdown (OTP). It also has UVLO for input rail and internal soft-start ramp. The SiP12107 is available in lead (Pb)-free power enhanced MLP-16L package in 3 mm x 3 mm dimension.
