No external ESR network required Ultrafast transient response DESCRIPTION Power saving scheme for increased light load efficiency The SiP12110 is a high frequency current-mode constant 1 % accuracy of V setting OUT on-time (CM-COT) synchronous buck regulator with integrated high-side and low-side power MOSFETs. Its Cycle-by-cycle current limit power stage is capable of supplying 6 A continuous current Fully protected with OTP, SCP, UVP, OVP at 1.0 MHz switching frequency. This regulator produces an P indicator GOOD adjustable output voltage down to 0.6 V from 4.5 V to 15 V -40 C to +125 C operating junction temperature input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and Output voltage tracking industrial. Material categorization: for definitions of compliance SiP12110s CM-COT architecture delivers ultrafast transient please see www.vishay.com/doc 99912 response with minimum output capacitance and tight ripple regulation at very light load. The part is stable with any APPLICATIONS capacitor type and no ESR network is required for loop Point of load regulation for low-power processors, stability. The device also incorporates a power saving network processors, DSPs, FPGAs, and ASICs scheme that significantly increases light load efficiency. Low voltage, distributed power architectures with 5 V The regulator integrates a full protection feature set, or 12 V rails including output overvoltage protection (OVP), output unde r Computing, broadband, networking, LAN / WAN, optical, voltage protection (UVP) and thermal shutdown (OTP). It test and measurement also has UVLO for input rail and internal soft-start ramp. A/V, high density cards, storage, DSL, STB, DVR, DTV, The SiP12110 is available in lead (Pb)-free power enhanced Industrial PC 3 mm x 3 mm QFN16-33G package.
