Upgraded smart power stages support latest MPUs
Vishay Intertechnology’s five new 70A, 80A and 100A VRPower Smart Power Stages are in stock at New Yorker Electronics.
They offer integrated current and temperature monitors in the thermally enhanced PowerPAK MLP56-39L package.
Designed to reduce energy costs for data centres and other high performance computing and 5G mobile telecom infrastructure applications, New Yorker Electronics says that the Vishay Siliconix SiC820, SiC822, SiC830, SiC832 and SiC840 deliver the industry’s highest energy efficiency and current reporting accuracy.
The new devices provide continuous currents of 70A (SiC822 and SiC832), 80A (SiC820 and SiC830) and 100A (SiC840).
The devices’ high energy efficiency is a result of their internal integrated Schottky diode in LS MOSFETs’ state of the art TrenchFET Gen IV technology, which delivers industry benchmark performance to significantly reduce switching and conduction losses.
While solutions that monitor power consumption using inductor DCR sensing offer current reporting accuracy of seven percent, the SiC820, SiC822, SiC830, SiC832 and SiC840 utilise low side MOSFET sensing for accuracy of less than -3 %.
This translates into better performance and improved thermal management in Intel Xeon, AMD Epyc, and other high current processors and SoCs.
The Vishay 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 (IMON) and Temperature Monitor (TMON).
The device is offered in the thermally enhanced 5 mm by 6 mm PowerPAK MLP56-39L package.
A diode emulation mode can be enabled at light loads for high efficiency over the full load range using the GLCTRL pin. High switching frequencies are up to 2 MHz.
Fault protection features include High side MOSFET short and overcurrent alerts, Over-temperature protection and Undervoltage lockout (UVLO)
The device supports 3.3 V and 5 V PWM logic with tri-state for compatibility with a wide range of PWM controllers
Applications include Synchronous Buck Converters, Multi-phase VRDs for CUPs, GPUs and Memory and DC/DC VR Modules
