Vishay Siliconix
50 A VRPower^® Integrated Power Stage
DESCRIPTION
The SiC632 and SiC632A are integrated power stage
solutions optimized for synchronous buck applications to
offer high current, high efficiency, and high power density
performance. Packaged in Vishay’s proprietary 5 mm x 5 mm
MLP package, SiC632 and SiC632A enables voltage
regulator designs to deliver up to 50 A continuous current
per phase.
The internal power MOSFETs utilizes Vishay’s
state-of-the-art Gen IV TrenchFET technology that delivers
industry benchmark performance to significantly reduce
switching and conduction losses.
The SiC632 and SiC632A incorporate an advanced
MOSFET gate driver IC that features high current driving
capability, adaptive dead-time control, an integrated
bootstrap Schottky diode, a thermal warning (THWn) that
alerts the system of excessive junction temperature, and
zero current detection to improve light load efficiency. The
drivers are also compatible with a wide range of PWM
controllers and supports tri-state PWM, 3.3 V (SiC632A) /
5 V (SiC632) PWM logic.
