DrMOS Integrated Power Stage
DESCRIPTION
FEATURES
The SiC770 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, SiC770
enables voltage regulator design to deliver in excess of 40 A
per phase current.
• Industry benchmark MOSFET with integrated
Schottky diode
• Delivers in excess of 40 A continuous current
• 91 % peak efficiency
• High frequency operation up to 1 MHz
• Power MOSFETs optimized for 19 V input stage
• 5 V PWM logic with tri-state and hold-off
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.
• Automatic skip mode operation (ZCD) for light load
efficiency
The SiC770 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
(ZCD) for improve light load efficiency.
• Built-in bootstrap Schottky diode
• Thermal monitor flag
• VCIN under voltage lockout
• Compliant with Intel DrMOS 4.0 specification
• Thermally enhanced PowerPAK® MLP6x6-40L package
• Material categorization: For definitions of compliance
