SiC780, SiC780A

Vishay Siliconix

Integrated DrMOS Power Stage

DESCRIPTION

FEATURES

The SiC780 is an integrated power stage solution optimized

for synchronous buck applications offering high current, high

efficiency and high power density. Packaged in Vishay's

proprietary 6 mm x 6 mm MLP package, SiC780 enables

voltage regulator designs to deliver in excess of 50 A per

phase current with 93 % peak efficiency.

The internal Power MOSFETs utilize Vishay’s state-of-the-art

TrenchFET Gen III Technology that delivers industry bench-

mark performance by significantly reducing switching and

conduction losses.

•

Thermally enhanced PowerPAK MLP6x6-40L

package

Industry benchmark MOSFET with integrated

schottky diode

Delivers in excess of 50 A continuous current

93 % peak efficiency

High frequency operation up to 1 MHz

Power MOSFETs optimized for 12 V input stage

3.3 V (SiC780ACD)/5 V (SiC780CD) PWM logic with

Tri-state and hold-off

•

The SiC780 incorporates an advanced MOSFET gate driver

IC that features high current driving capability, adaptive

dead-time control, and integrated bootstrap Schottky diode,

and a thermal warning (THDN) that alerts the system of

excessive junction temperature. The driver is also compatible

with a wide range of PWM controllers and supports Tri-state

PWM, 3.3 V(SiC780ACD)/5 V (SiC780CD) PWM Logic, and

skip mode (SMOD) to improve light load efficiency.

•

SMOD logic for light load efficiency boost

Low PWM propagation delay (< 20 ns)

Thermal monitor flag

Enable feature

V_CINUVLO

Compliant with Intel DrMOS 4.0 specification

Material categorization: For definitions of compliance
