SiC769ACD
Vishay Siliconix
Integrated DrMOS Power Stage
DESCRIPTION
The SiC769ACD 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 V core power
stages. The SiC769ACD 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 2.0 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 SiC769ACD incorporates an advanced MOSFET gate
driver IC. This IC accepts a single PWM input from the V R
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
SiC769ACD 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 SiC769ACD is optimized for high frequency buck
applications. Operating frequencies in excess of 1 MHz can
easily be achieved.
The SiC769ACD 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.
