SIC653ACD-T1-GE3

The SiC653 and SiC653A are integrated power stage solutions from Vishay, designed for synchronous buck applications requiring high current, high efficiency, and high power density. Packaged in Vishay’s proprietary 5 mm x 5 mm MLP package, these devices enable voltage regulator designs to deliver up to 50 A continuous current per phase.

Utilizing Vishay’s state-of-the-art Gen IV TrenchFET technology, the internal power MOSFETs significantly reduce switching and conduction losses. The integrated MOSFET gate driver IC features high current driving capability, adaptive dead-time control, an integrated bootstrap Schottky diode, and a thermal warning (THWn) to alert the system of excessive junction temperature. Zero current detect is incorporated to improve light load efficiency.

The SiC653 and SiC653A are compatible with a wide range of PWM controllers and support tri-state PWM. They operate at high frequencies up to 1.5 MHz and are optimized for 12 V input stages. The package is a thermally enhanced PowerPAK MLP55-31L, suitable for surface mount applications.

Key features include up to 50 A continuous current, 95 % peak efficiency, low PWM propagation delay (< 20 ns), and under-voltage lockout protection. The SiC653 supports 5 V PWM logic, while the SiC653A supports 3.3 V PWM logic, both with tri-state and hold-off capabilities.
