The SIC779CD-T1-GE3 is an integrated DrMOS Power Stage Solution optimized for high frequency buck applications. Operating frequencies in excess of 1MHz can easily be achieved. It contains PWM optimized n-channel MOSFETs (high-side and low-side) and a full featured MOSFET driver IC. The device complies with the Intel DrMOS standard for desktop and server Vcore power stages. The SiC779 delivers up to 40A continuous output current and operates from an input voltage range of 3 to 16V. The integrated MOSFETs are optimized for output voltages in the ranges of 0.8 to 2V with a nominal input voltage of 12V. The device can also deliver very high power at 5V output for ASIC applications. It incorporates an advanced MOSFET gate driver IC. This IC accepts a single PWM input from the VR controller and converts it into the high-side and low-side MOSFET gate drive signals.
