Vishay Siliconix SiC779 Integrated DrMOS Power Stage

Vishay Siliconix SiC779
Integrated DrMOS Power Stage

Vishay Siliconix SiC779 Integrated DrMOS Power Stage is an integrated solution that contains PWM optimized n-channel MOSFETs (high side and low side) and a full featured MOSFET driver IC. The Vishay Siliconix SiC779 complies with the Intel DrMOS standard for desktop and server Vcore power stages. The SiC779 Integrated DrMOS Power Stage delivers up to 40A continuous output current and operates from an input voltage range of 3V to 16V. The integrated MOSFETs are optimized for output voltages in the ranges of 0.8V to 2.0V with a nominal input voltage of 12V. The device can also deliver very high power at 5V output for ASIC applications. The Vishay Siliconix SiC779 is optimized for high frequency buck applications. Operating frequencies in excess of 1MHz can easily be achieved.
