60-A multi-chip module family enables designers to meet stringent energy savings standards

April 17, 2012 // By Paul Buckley
Fairchild Semiconductor has developed the FDMF68xx Gen III DrMOS multi-chip module (MCM) family to meet the demands of new energy standards combined with new system specifications for blade servers, high performance notebooks, gaming consoles and POL modules.

Designed to enable a reduced inductor and output capacitor count, the FDMF68xx series saves up to 50 percent of board space as compared to conventional discrete solutions and improves efficiency to meet new energy standards. The FDMF68xx series reduces switch ringing, using Fairchild's high-performance PowerTrench MOSFET technology to eliminate the need for using a snubber circuit in most buck converter applications.

The Gen III DrMOS MCM family supports both 3.3 V and 5 V Tri-State PWM input voltages for both digital and analog PWM controllers and a 30 V device option makes the DrMOS adaptable for Notebook or UltraBook power systems. Providing better efficiency with over 1 MHz switching frequency, increased maximum load current, and greater power density, the Gen III DrMOS series achieves efficiency standards targets while providing up to 60 A per phase in a 6x6 mm2 PQFN package.
