SiC820, SiC820A www.vishay.com Vishay Siliconix 80 A VRPower , Smart Power Stage With Current Sensing and Temperature Monitor (Datasheet in Brief) FEATURES Thermally enhanced PowerPAK MLP39-65 package Optimize MOSFET switching performance with integrated Schottky diode in LS MOSFET Up to 80 A continuous current High frequency operation up to 2 MHz Power MOSFETs optimized for 12 V input stage and 10 % to 15 % duty cycle operation 3.3 V / 5 V PWM logic with tri-state and hold-off PWM minimum controllable on time of 30 ns DESCRIPTION Diode emulation mode at light loads for high efficiency The SiC820 is an integrated power stage solution optimize d over the full load range using GLCTRL pin for synchronous buck applications to offer high current, high Low PWM propagation delay (< 20 ns) efficiency, and high power density performance. Packaged Current sense monitor (I ) MON in Vishay s 5 mm x 6 mm MLP package, SiC820 enables Temperature monitor (T ) MON voltage regulator design to deliver in excess of 80 A pe r Over temperature alert phase current. HS MOSFET over-current and short alert The internal power MOSFETs utilize Vishay s Under voltage lockout for V state-of-the-art TrenchFET Gen IV technology that delivers DRV industry bench mark performance to significantly reduce Material categorization: for definitions of compliance switching and conduction losses. please see www.vishay.com/doc 99912 The SiC820 incorporates an advanced MOSFET gate driver APPLICATIONS IC that features high current driving capability, adaptive dead-time control, and integrated bootstrap switch, a Synchronous buck converters thermal monitor that alerts the system of excessive junction Multi-phase VRDs for CPU, GPU, and memory temperature. This driver is also compatible with wide rang e DC/DC VR modules of PWM controllers with the support of both 3.3 V and 5 V PWM logic with tri-state. Diode emulation mode can be enabled at light loads through the use of GLCTRL signal. The device also integrates a current monitor to provide a real EFFICIENCY time scale down of inductor current (I ).
