SiC521, SiC521A
Vishay Siliconix
30 A VRPower® Integrated Power Stage
DESCRIPTION
The SiC521 and SiC521A are integrated power stage
solutions optimized for synchronous buck applications
to offer high current, high efficiency, and high power
density performance. Packaged in Vishay’s proprietary
4.5 mm x 3.5 mm MLP package, SiC521 and SiC521A
enable voltage regulator designs to deliver up to 30 A
continuous current per phase.
The internal power MOSFETs utilize Vishay’s
state-of-the-art Gen IV TrenchFET technology that delivers
industry benchmark performance to significantly reduce
switching and conduction losses.
The SiC521 and SiC521A incorporate an advanced
MOSFET gate driver IC that features high current driving
capability, adaptive dead-time control, an integrated
bootstrap Schottky diode, and zero current detect to
improve light load efficiency. The drivers are also
compatible with a wide range of PWM controllers, support
tri-state PWM, and 3.3 V (SiC521A) / 5 V (SiC521) PWM
logic.
FEATURES
• Thermally enhanced PowerPAK® MLP4535-22L
package
• Vishay’s Gen IV MOSFET technology and a
low-side MOSFET with integrated Schottky
diode
• Delivers up to 30 A continuous current, 40 A at 10 ms peak
current
• 95 % peak efficiency
• High frequency operation up to 1.5 MHz
• Power MOSFETs optimized for 12 V input stage
• 3.3 V (SiC521A) / 5 V (SiC521) PWM logic with tri-state and
hold-off
• Zero current detect control for light load efficiency
improvement
• Low PWM propagation delay (< 20 ns)
• Under voltage lockout for VCIN
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Multi-phase VRDs for CPU, GPU, and memory
• Synchronous buck converters
• DC/DC VR modules
