SIC780 Datasheet, PDF (1/14 Pages) Vishay Siliconix – Integrated DrMOS Power Stage

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 bench-
mark 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.
