B, 09-Feb-15 1 Document Number: 62989 For technical questions, contact: powerictechsupport@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 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 TYPICAL APPLICATION DIAGRAM Fig. 1 - SiC521 and SiC521A Typical Application Diagram PWM controller Gate driver 5V VIN VOUT VCIN ZCD_EN# PWM BOOT VSWH PHASE |
