SIC53/SIC63 VRPOWER® Integrated Power Stage

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
Features
  • Combine power MOSFETs, advanced MOSFET gate driver IC, and a bootstrap Schottky diode
  • High-power density:
    • Continuous current to 30 A in the 4.5 mm by 3.5 mm PowerPAK MLP4535-22L package
    • Continuous current to 40 A in the 5 mm by 5 mm PowerPAK MLP55-31L package
  • Support PS4 mode light-load requirements for IMVP8
  • RoHS-compliant and halogen-free
  • Lower package parasitic enable switching frequencies up to 2 MHz
  • Driver IC is compatible with a wide range of PWM controllers and supports tri-state PWM logic of 5 V
  • High efficiency:
    • Diode emulation mode circuity and zero-current detect increase light-load efficiency
    • Adaptive dead time control improves efficiency at all load points
  • Feature under-voltage lockout (UVLO)
Applications
  • DC/DC voltage regulation modules
  • Multiphase VRDs for CPUs, GPUs, and memory in next-generation notebooks, Ultrabooks, desktops, and workstations
  • Power delivery for high-performance ASICs and FPGAs in embedded systems
  • Cloud computing
  • Telecom/networking infrastructure
  • Industrial PCs
  • Synchronous buck converters
