Vishay Intertechnology VRPower® Integrated DrMOS Power Stages Deliver High Power Density and Efficiency for Notebooks, Ultrabooks, and Desktops

MALVERN, Pa., Jan. 14, 2016 (GLOBE NEWSWIRE) -- To meet the need for high-current, high-efficiency, and high-power-density performance in next-generation notebooks, ultrabooks, and desktops, Vishay Intertechnology, Inc. (NYSE:VSH) today introduced five new VRPower® integrated DrMOS power stage solutions for multiphase POL regulator applications. Combining power MOSFETs, an advanced MOSFET gate driver IC, and a bootstrap Schottky diode in thermally enhanced 4.5 mm by 3.5 mm PowerPAK® MLP4535-22L and 5 mm by 5 mm PowerPAK MLP55-31L packages, the Vishay Siliconix SiC530CD, SiC531CD, SiC532CD, SiC631CD, and SiC632CD offer a 45 % smaller footprint compared with discrete solutions. The devices’ high power density is optimized for computing platforms using the Intel® Skylake platform. The devices are also suitable for industrial PC and high-current multiphase modules used in networking and industrial applications.

Today’s mobile and desktop platforms require higher currents than their predecessors, while consumers demand ever-smaller form factors. The integrated devices released today offer continuous current up to 30 A in the 4.5 mm by 3.5 mm PowerPAK MLP4535-22L package and 40 A in the 5 mm by 5 mm PowerPAK MLP55-31L package. In addition to their high-current capabilities and footprint savings, the power stages also lower package parasitics to enable switching frequencies up to 2 MHz — further shrinking the overall solution size and profile by reducing the size of the output filter. For high performance, the devices’ high- and low-side MOSFETs utilize Vishay’s state-of-the-art Gen IV TrenchFET® technology to reduce switching and conduction losses. The power stages’ driver IC is compatible with a wide range of PWM controllers and supports tri-state PWM logic of 5 V.

The SiC530CD, SiC531CD, SiC532CD, SiC631CD, and SiC632CD are optimized for synchronous buck converters, DC/DC voltage regulation modules, and multiphase VRDs for CPUs, GPUs, and memory. To increase light-load efficiency in these applications, the devices’ driver IC incorporates diode emulation mode circuity and zero-current detect. An adaptive dead time control helps to further improve efficiency at all load points. To support PS4 mode light-load requirements for IMVP8, the power stages reduce current consumption to 5 µA when systems are operating in standby mode, and they can be woken from this state within 5 µs. Protection features for the RoHS-compliant, halogen-free devices include undervoltage lockout (UVLO).
