Generation III XSâ¢ DrMOS Family

Advantages

â¢ 93% at peak and 91% at 30A,

500KHz frequency; 12VIN, 1VOUT

â¢ 90% at peak and 88% at 30A,

1MHz frequency; 12VIN, 1VOUT

â¢ High current handling:

60A @ 100Â°C TJ

â¢ Capable of operating up to

1.5MHz switching frequency

â¢ Eliminates need for a

heat sink in typical designs

Highest Power Efficiency with the DrMOS Family

Achieve improved efficiency with >1MHz switching frequencies, increased maxi-

mum load current and greater power density with Fairchildâs Generation III XSâ¢

DrMOS multi-chip mode module family. The FDMF68xx family achieves effi-

ciency standards targets, while providing up to 60A per phase in a 6mm x 6mm

PQFN package. Both 3.3V and 5V Tri-State PWM input voltages for digital and

analog PWM controllers, and a 30V device option make the DrMOS family a

good choice for use in UltraBookâ¢ systems.

Designed to enable a reduced inductor and output capacitor count, the

FDMF68xx series saves up to 50% of board space as compared to conventional

discrete solutions. The FDMF68xx series dramatically reduces switch ringing,

using Fairchildâs high-performance PowerTrenchÂ® MOSFET technology, elimi-

nating the need for using a snubber circuit in most buck converter applications.

Applications

â¢ Notebook or UltraBookâ¢

power systems
