60 A VRPower^®Integrated Power Stage

DESCRIPTION

FEATURES

• Thermally enhanced PowerPAK^®MLP66-40L

package

The SiC789 and SiC789A 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

6 mm x 6 mm MLP package, SiC789 and SiC789A enable

voltage regulator designs to deliver up to 60 A continuous

current per phase.

• Vishay’s Gen IV MOSFET technology and a

low-side MOSFET with integrated Schottky

diode

• Delivers up to 60 A continuous current

• 95 % peak efficiency

The

Vishay’s

• High frequency operation up to 1.5 MHz

• Power MOSFETs optimized for 12 V input stage

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

industry benchmark performance to significantly reduce

switching and conduction losses.

• 3.3 V (SiC789A) / 5 V (SiC789) PWM logic with tri-state and

hold-off

The SiC789 and SiC789A incorporate an advanced

MOSFET gate driver IC that features high current driving

capability, adaptive dead-time control, an integrated

bootstrap Schottky diode, a thermal warning (THWn) that

alerts the system of excessive junction temperature, and

skip mode (SMOD#) to improve light load efficiency. The

drivers are also compatible with a wide range of PWM

controllers and supports tri-state PWM, 3.3 V (SiC789A) /

5 V (SiC789) PWM logic.

• SMOD# logic for light load efficiency improvement

• Low PWM propagation delay (< 20 ns)

• Thermal monitor flag

• Faster enable / disable

• Under voltage lockout for V_CIN

• Material categorization: for definitions of compliance
