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.
