SiC772CD
Vishay Siliconix
DrMOS Integrated Power Stage
DESCRIPTION
FEATURES
The SiC772 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 6 mm x 6 mm MLP package, SiC772
enables voltage regulator design to deliver in excess of 40 A
per phase current.
The internal Power MOSFETs utilizes Vishay’s state-of-the-
art TrenchFET Gen IV technology that delivers industry
bench-mark performance to significantly reduce switching
and conduction losses.
The SiC772 incorporates an advanced MOSFET gate driver
IC that features high current driving capability, adaptive
dead-time control, and integrated bootstrap Schottky diode;
a thermal warning (THWn) alerts the system of excessive
junction temperature. This driver is also compatible with wide
range of PWM controllers with the support of Tri-state PWM,
5 V PWM Logic, and skip mode (SMOD) for improve light
load efficiency.
