50 A, VRPower^®Integrated Power Stage

DESCRIPTION

FEATURES

The SiC781 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 MLP 6 mm x 6 mm package, SiC781

enables voltage regulator designs to deliver currents up to

50 A per phase.

• Thermally enhanced PowerPAK^®MLP66-40L package

• Industry benchmark MOSFET with integrated Schottky

diode

• Delivers up to 50 A continuous current

• Pin and functionally compatible with NCP5369N

• High frequency operation up to 1 MHz

• Optimized for 12 V input rail applications

• 5 V PWM logic with tri-state threshold

The

internal

power

MOSFETs

utilize

Vishay’s

state-of-the-art trench MOSFET technology that delivers

industry benchmark performance to significantly reduce

switching and conduction losses.

• Zero current detection and low side MOSFET turn off

during discontinuous mode

The SiC781 incorporates an advanced MOSFET gate driver

IC that features high current driving capability, adaptive

dead-time control, an integrated bootstrap Schottky diode,

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

excessive junction temperature. This driver is compatible

with wide range of PWM controllers and supports tri-state

PWM logic (5 V) as well as zero current detection to improve

light load efficiency.

• Short PWM propagation delay (< 20 ns)

• Supports Intel PS2 requirement with ON Semiconductor’s

NCP5133 and NCP6133 controllers

• Thermal monitor flag

• Faster enable / disable

• V_CINunder voltage lock out (UVLO)

APPLICATIONS

• Synchronous buck converters

• Multi-phase VRDs for CPU, GPU and memory

• DC/DC POL modules
