Smart power stages increase efficiency and accuracy

New Yorker Electronics has released Vishay Intertechnology’s five new 70A, 80A and 100A VRPower Smart Power Stages with integrated current and temperature monitors in a thermally enhanced PowerPAK MLP56-39L package.

Intended to decrease energy costs for data centres and other high-performance computing and 5G mobile telecom infrastructure applications, the Vishay Siliconix SiC820, SiC822, SiC830, SiC832 and SiC840 provide the industry’s highest energy efficiency and current reporting accuracy. The new devices offer continuous currents of 70A (SiC822 and SiC832), 80A (SiC820 and SiC830) and 100A (SiC840).

The devices’ high energy efficiency results from their internal integrated Schottky diode in LS MOSFETs' state-of-the-art TrenchFET Gen IV technology, providing industry benchmark performance to noticeably lessen switching and conduction losses. While solutions that monitor power consumption utilising inductor DCR sensing offer current reporting accuracy of 7%, the SiC820, SiC822, SiC830, SiC832 and SiC840 utilise low side MOSFET sensing for accuracy of less than 3%. This translates into greater performance and enhanced thermal management in Intel Xeon, AMD Epyc, and other high current processors and SoCs.

The SiC820, SiC822 and SiC840 supply an input voltage range of 4.5V to 16V. The SiC830 and SiC832 attain a range of 4.5V to 21V. Built-in protections include its Current Sense Monitor and Temperature Monitor.
