SIC780

SiC780, SiC780A Vishay Siliconix Integrated DrMOS Power Stage DESCRIPTION The SiC780 is an integrated power stage solution optimized for synchronous buck applications offering high current, high efficiency and high power density. Packaged in Vishay's proprietary 6 mm x 6 mm MLP package, SiC780 enables voltage regulator designs to deliver in excess of 50 A per phase current with 93 % peak efficiency. The internal Power MOSFETs utilize Vishay’s state-of-the-art TrenchFET Gen III Technology that delivers industry benchmark performance by significantly reducing switching and conduction losses. The SiC780 incorporates an advanced MOSFET gate driver IC that features high current driving capability, adaptive dead-time control, and integrated bootstrap Schottky diode, and a thermal warning (THDN) that alerts the system of excessive junction temperature. The driver is also compatible with a wide range of PWM controllers and supports Tri-state PWM, 3.3 V(SiC780ACD)/5 V (SiC780CD) PWM Logic, and skip mode (SMOD) to improve light load efficiency. FEATURES Thermally enhanced PowerPAK MLP6x6-40L package Industry benchmark MOSFET with integrated schottky diode Delivers in excess of 50 A continuous current 93 % peak efficiency High frequency operation up to 1 MHz Power MOSFETs optimized for 12 V input stage 3.3 V (SiC780ACD)/5 V (SiC780CD) PWM logic with Tri-state and hold-off SMOD logic for light load efficiency boost Low PWM propagation delay (< 20 ns) Thermal monitor...
