Vishay Siliconix SIC781CD-T1-GE3

Description
The SIC781 is an integrated power stage solution designed for synchronous buck applications. It offers high current, high efficiency, and high power density performance. Packaged in Vishay's proprietary MLP 6 mm x 6 mm package, the 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, delivering 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 a wide range of PWM controllers and supports tri-state PWM logic (5 V) as well as zero current detection to improve light load efficiency.
