Vishay Siliconix
50 A, VRPower® Integrated Power Stage
DESCRIPTION
The SiC783A is an integrated power stage solution
optimized for synchronous buck applications to offer
high current, high efficiency and high power density
performance. Packaged in Vishay’s proprietary MLP 6 mm
x 6 mm package, SiC783A enables voltage regulator
designs to deliver currents up to 50 A per phase.
The internal power MOSFETs utilize Vishay’s
state-of-the-art trench MOSFET technology that delivers
industry benchmark performance to significantly reduce
switching and conduction losses.
The SiC783A incorporates an advanced MOSFET gate
driver IC that features high current driving capability,
adaptive dead-time control, an integrated bootstrap
Schottky diode, and a thermal warning (THWn) that alerts
the system of excessive junction temperature. This driver is
compatible with wide range of PWM controllers and
supports tri-state PWM logic (3.3 V) as well as zero current
detect to improve light load efficiency.
FEATURES
• Thermally enhanced PowerPAK® MLP66-40L package
• Industry benchmark MOSFET with integrated Schottky
diode
• Delivers up to 50 A continuous current
• High frequency operation up to 1 MHz
• Optimized for 12 V input rail applications
• 3.3 V PWM logic with tri-state threshold
• Zero current detect control for light load efficiency
improvement.
• Short PWM propagation delay (< 20 ns)
• Thermal monitor flag
• Faster disable
• VCIN under voltage lock out (UVLO)
APPLICATIONS
• Synchronous buck converters
• Multi-phase VRDs for CPU, GPU and memory
• DC/DC POL modules

Notes
• Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
(1) The specification values indicate “AC voltage” is VSWH to PGND, -7 V (< 50 ns, 10 μJ), minimum and 27 V (< 50 ns), maximum.
(2) The specification value indicates “AC voltage” is VBOOT to PGND, 34 V (< 50 ns) maximum.
(3) The specification value indicates “AC voltage” is VBOOT to VPHASE, 8 V (< 20 ns) maximum.
