SiC780, SiC780A  
Vishay Siliconix  
Integrated DrMOS Power Stage  
DESCRIPTION  
FEATURES  
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.  
Thermally enhanced PowerPAK MLP6x6-40L  
package  
Industry benchmark MOSFET with integrated  
schottky diode  
Delivers in excess of 50 A continuous current  
93 % peak efficiency  
High frequency operation up to 1 MHz  
Power MOSFETs optimized for 12 V input stage  
3.3 V (SiC780ACD)/5 V (SiC780CD) PWM logic with  
Tri-state and hold-off  
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.  
SMOD logic for light load efficiency boost  
Low PWM propagation delay (< 20 ns)  
Thermal monitor flag  
Enable feature  
VCIN UVLO  
Compliant with Intel DrMOS 4.0 specification  
Material categorization: For definitions of compliance
