www.vishay.com SiC781CD Vishay Siliconix 50 A, VRPower® Integrated Power Stage DESCRIPTION The SiC781 is an integrated power stage solution optimized for synchronous buck applications to offer high current, high efficiency and high power density performance. Packaged in Vishay’s proprietary MLP 6 mm x 6 mm package, SiC781 enables voltage regulator designs to deliver currents up to 50 A per phase. The internal power MOSFETs utilize Vishay’s state-of-the-art trench MOSFET technology that delivers industry benchmark performance to significantly reduce switching and conduction losses. The SiC781 incorporates an advanced MOSFET gate driver IC that features high current driving capability, adaptive dead-time control, an integrated bootstrap Schottky diode, and a thermal warning (THWn) that alerts the system of excessive junction temperature. This driver is compatible with wide range of PWM controllers and supports tri-state PWM logic (5 V) as well as zero current detection to improve light load efficiency. FEATURES Thermally enhanced PowerPAK® MLP66-40L package Industry benchmark MOSFET with integrated Schottky diode Delivers up to 50 A continuous current Pin and functionally compatible with NCP5369N High frequency operation up to 1 MHz Optimized for 12 V input rail applications 5 V PWM logic with tri-state threshold Zero current detection and low side MOSFET turn off during discontinuous mode Short PWM propagation delay (< 20 ns) Supports Intel PS2 requirem...
