Footprint-compatible with the common SOD-128, the SlimSMAW package features larger lead widths and shorter lengths than devices in the SlimSMA for AOI systems and increased reliability. Available in AEC-Q101 qualified versions, the devices offer low forward voltage drop to reduce power losses and increase efficiency.
microBUCK® and microBRICK™ Buck Regulators With PMBus Interfaces and High Peak Efficiency
The Vishay Siliconix microBUCK® SiC451 and microBRICK™ SiC951 combine high performance trench MOSFETs in compact 5 mm by 7 mm and 10.6 mm by 6.5 mm by 3 mm thermally efficient packages, respectively, with the SiC951 also offering an integrated inductor. Both devices support over 50 PMBus commands. Capable of supplying up to 30 A of continuous output current and offering peak efficiency up to 96 %, the buck regulators’ output voltage is digitally adjustable from 0.3 V to 5.5 V with 1 % output voltage accuracy.
VRPower® Smart Power Stages Increase Efficiency and Accuracy to Lower Energy Costs for Server Farms and Computing Applications
The 80 A SiC820 and SiC830 feature integrated current and temperature monitors in the thermally enhanced PowerPAK® MLP56-39L package. While solutions that monitor power consumption using inductor DCR sensing offer current reporting accuracy of 7 %, the Vishay Siliconix solutions utilize low side MOSFET sensing for accuracy of < 3 %. This translates into better performance and improved thermal management in high current processors.
