To meet the need for high current, high-efficiency, and high-power-density performance in next-generation notebooks, Ultrabooks, and desktops, Vishay Siliconix introduces five 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 SiC530, SiC531, SiC532, SiC631, and SiC632 offer a 45% smaller footprint compared to utilizing discrete solutions.
- Optimized for computing platforms utilizing Intel’s Skylake platform
- High switching frequencies shrink the overall solution size and profile by reducing the size of the output filter
- High- and low-side MOSFETs utilize Vishay’s state-of-the-art Gen IV TrenchFET® technology to reduce switching and conduction losses
- Reduce current consumption to 5 µA when systems are operating in standby mode, and can be woken from this state within 5 µs
