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.

Note
(1) The specification values indicated “AC” is VSWH to PGND, -8 V (< 20 ns, 10 μJ), min. and 30 V (< 50 ns), max.
(2) The specification value indicates “AC voltage” is VBOOT to PGND, 36 V (< 50 ns) max.
(3) The specification value indicates “AC voltage” is VBOOT to VPHASE, 8 V (< 20 ns) max.
(4) Output current rated with testing evaluation board at TA = 25 °C with natural convection cooling. The rating is limited by the peak evaluation
board temperature, TJ = 150 °C, and varies depending on the operating conditions and PCB layout. This rating may be changed with different
application settings.
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.
