DESCRIPTION The SiC654 and SiC654A are high frequency integrated power stage optimized for synchronous buck applications to offer high current, high efficiency, and high power density performance with very low shutdown current. Packaged in Vishay’s 5 mm x 5 mm MLP package, SiC654 and SiC654A enable voltage regulator designs to deliver up to 50 A continuous current per phase. The internal power MOSFETs utilize Vishay’s latest TrenchFET® technology that delivers industry benchmark performance to significantly reduce switching and conduction losses. The SiC654 and SiC654A incorporates an advanced MOSFET gate driver IC that features high current driving capability, adaptive dead-time control, an integrated bootstrap switch, and user selectable zero current detection to improve light load efficiency. The driver is also compatible with a wide range of PWM controllers, supports tri-state PWM, and 5 V / 3.3 V PWM logic. The device also supports PS4 mode to reduce power consumption when the system is in standby state. The SiC654 and SiC654A offer operating temperature monitoring, protection features, and warning flags that improve system monitoring and reliability.
