Description

The XS™ Dr MOS family is ON Semiconductor ’s next-

generation, fully optimized, ultra-compact, integrated

MOSFET plus driver pow er stage solution for high-

current, high-frequency, synchronous

buc k

DC- DC

applications. The FDMF6840C integrates a driver IC,

tw o pow er MOSFETs, and a bootstrap Schottky diode

into a

ther mally

enhanced, ultra-compact

6x6 mm

package.

With an integrated approach, the complete sw itching

pow er stage is optimized w ith regard to dr iver and

MOSFET dynamic performance, system inductance,

and pow er MOSFET RDS(ON). XS™ Dr MOS uses ON

Semiconductor's

high-perfor mance

Pow erTrench

®

MOSFET technology, w hich dramatically reduces sw itch

ringing, eliminating the need for snubber circuit in most

buck converter applications.

A driver IC w ith reduced dead times and propagation

delays further enhances the performance. A thermal

w arning function w arns of a potential over-temperature

situation. The FDMF6840C also incorporates a Skip

Mode ( SMOD#) for improved light- load efficiency. The

FDMF6840C also provides a 3-state 3.3 V PWM input

for compatibility w ith a w ide range of PWM controllers.

Applications

 High-Performance Gaming Motherboards

 Compact Blade Servers, V-Core and Non-V-Core

DC-DC Converters

 Desktop Computers, V-Core and Non-V-Core

DC-DC Converters

 Workstations

 High-Current DC-DC Point-of-Load Converters

 Netw orking and Telecom Microprocessor Voltage

Regulators

 Small Form-Factor Voltage Regulator Modules
