San Jose, Calif. Fairchild Semiconductor has released the FDMF8704 and FDMF8704V driver plus FET (DrMOS) modules that minimize power losses across all load levels in DC/DC applications. These devices are said to optimize efficiency across high, medium and light loads in ultra-dense servers, blade servers, advanced gaming systems, small form factor desktops, media center PCs, graphic cards, networking and telecom equipment, and other DC-DC applications.
Fairchild claims these driver plus FET modules can reduce average power losses across the full operating range by 14 percent compared to conventional discrete solutions. In addition, these multi-chip modules can more easily meet the demand for higher efficiency mandated by energy regulatory programs such as Energy Star, said the company.
The FDMF8704 and FDMF8704V are FET plus driver power stage solutions that integrate one driver IC, three power MOSFETs and one Schottky diode into an 8 x 8-mm MLP package. The FDMF8704 is capable of operating at 1 MHz, eliminating passive components to further reduce board space and lower bill-of-materials (BOM) costs. Compared to conventional discrete solutions, the DrMOS module saves more than 72 percent of board space, according to Fairchild.
The FDMF8704 and the FDMF8704V are both based on the Intel specification for DrMOS. The FDMF8704 maximizes efficiency through a low-impedance driver IC and Fairchild's latest PowerTrench MOSFET technology. The FDMF8704 is suitable for server applications. The FDMF8704V features a built-in voltage regulator block for applications with only a 12-V rail available.
The FDMF8704 and FDMF8704V use lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are RoHS compliant.
