DrMOS Integrated Power Stage

DESCRIPTION

FEATURES

The SiC770 is an integrated power stage solution optimized

for synchronous buck applications to offer high current, high

efficiency and high power density performance. Packaged

in Vishay’s proprietary 6 mm x 6 mm MLP package, SiC770

enables voltage regulator design to deliver in excess of 40 A

per phase current.

• Industry benchmark MOSFET with integrated

Schottky diode

• Delivers in excess of 40 A continuous current

• 91 % peak efficiency

• High frequency operation up to 1 MHz

• Power MOSFETs optimized for 19 V input stage

• 5 V PWM logic with tri-state and hold-off

The internal power MOSFETs utilizes Vishay’s

state-of-the-art TrenchFET Gen IV technology that delivers

industry bench-mark performance to significantly reduce

switching and conduction losses.

• Automatic skip mode operation (ZCD) for light load

efficiency

The SiC770 incorporates an advanced MOSFET gate driver

IC that features high current driving capability, adaptive

dead-time control, and integrated bootstrap Schottky

diode, a thermal warning (THWn) alerts the system of

excessive junction temperature. This driver is also

compatible with wide range of PWM controllers with the

support of tri-state PWM, 5 V PWM logic, and skip mode

(ZCD) for improve light load efficiency.

• Built-in bootstrap Schottky diode

• Thermal monitor flag

• V_CINunder voltage lockout

• Compliant with Intel DrMOS 4.0 specification

• Thermally enhanced PowerPAK^®MLP6x6-40L package

• Material categorization: For definitions of compliance

APPLICATIONS

• Synchronous buck converters

• Muliti-phase VRDs for CPU, GPU and memory

• DC/DC POL modules
