SiC531A

www.vishay.com SiC531, SiC531A Vishay Siliconix 30 A VRPower® Integrated Power Stage DESCRIPTION The SiC531 and SiC531A are integrated power stage solutions optimized for synchronous buck applications to offer high current, high efficiency, and high power density performance. Packaged in Vishay’s proprietary 4.5 mm x 3.5 mm MLP package, SiC531 and SiC531A enable voltage regulator designs to deliver up to 30 A continuous current per phase. The internal power MOSFETs utilize Vishay’s state-of-the-art Gen IV TrenchFET® technology that delivers industry benchmark performance to significantly reduce switching and conduction losses. The SiC531 and SiC531A incorporate an advanced MOSFET gate driver IC that features high current driving capability, adaptive dead-time control, an integrated bootstrap Schottky diode, and zero current detection to improve light load efficiency. The drivers are also compatible with a wide range of PWM controllers, support tri-state PWM, and 3.3 V (SiC531A) / 5 V (SiC531) PWM logic.
