Integrated DrMOS Power Stage
SiC769
Vishay Siliconix
DESCRIPTION
The SiC769CD is an integrated solution that 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 SiC769CD delivers up to 35 A continuous output
current and operates from an input voltage range of 3 V to
16 V. The integrated MOSFETs are optimized for output
voltages in the ranges of 0.8 V to 2 V with a nominal input
voltage of 12 V. The device can also deliver very high power
at 5 V output for ASIC applications.
The SiC769CD 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. The driver IC is designed to
implement the skip mode (SMOD) function for light load
efficiency improvement. Adaptive dead time control also
works to improve efficiency at all load points. The SiC769CD
has a thermal warning (THDN) that alerts the system of
excessive junction temperature. The driver IC includes an
enable pin, UVLO and shoot through protection.
The SiC769CD is optimized for high frequency buck
applications. Operating frequencies in excess of 1 MHz can
easily be achieved.
The SiC769CD is packaged in Vishay Siliconix high
performance PowerPAK MLP6 x 6 package. Compact
co-packaging of components helps to reduce stray
inductance, and hence increases efficiency.
