SiP12107 www.vishay.com Vishay Siliconix 5 V, 3 A Current-Mode Constant On-Time Synchronous Buck Regulator FEATURES 2.8 V to 5.5 V input voltage Adjustable output voltage down to 0.6 V 3 A continuous output current Programmable switching frequency up to 4 MHz 95 % peak efficiency Supports all ceramic capacitors,no external ESR required Ultrafast transient response Selectable power saving mode or force current mode DESCRIPTION 1 % accuracy The SiP12107 is a high frequency current-mode constant Pulse-by-pulse current limit on-time (CM-COT) synchronous buck regulator with Scalable with SiP12108 - 5A integrated high-side and low-side power MOSFETs. Its Fully protected with OTP, SCP, UVP, OVP power stage is capable of supplying 3 A continuous current P D Indicator GOO 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 PowerCAD Simulation software available at input rail to accommodate a variety of applications, www.vishay.com/power-ics/powercad-list/ including computing, consumer electronics, telecom, and Material categorization: for definitions of compliance industrial. please see www.vishay.com/doc 99912 SiP12107s CM-COT architecture delivers ultra-fast transient response with minimum output capacitance and APPLICATIONS tight ripple regulation at very light load. No ESR or external Notebook computers ESR network is required for loop stability purpose. The Desktop PCs and servers device also incorporates a power saving scheme that Handheld devices significantly increases light load efficiency. POLs for telecom The regulator integrates a full protection feature set, including output overvoltage protection (OVP), output unde r Consumer electronics voltage protection (UVP) and thermal shutdown (OTP). It Industrial and automation also has UVLO for input rail and internal soft-start ramp. The SiP12107 is available in lead (Pb)-free power enhanced QFN16-33G package in 3 mm x 3 mm dimension.
