www.DataSheet4U.com FDMF8704 High Current / High Frequency FET plus Driver Multi-chip Module November 2007 FDMF8704 Benefits „ Fully optimized system efficiency. Higher efficiency levels are achievable compared with conventional discrete components. „ Space savings of up to 50% PCB versus discrete solutions. „ Higher frequency of operation. „ Simpler system design and board layout. Reduced time in component selection and optimization. tm High Current / High Frequency FET plus Driver Multi-chip Module General Description The FDMF8704 is a fully optimized integrated Driver plus MOSFET power stage solution for high current synchronous buck DC-DC applications. The device integrates a driver IC and two Power MOSFETs into a space saving, MLP 8x8, 56-pin package. Fairchild Semiconductor’s integrated approach optimizes the complete switching power stage with regards to driver to FET dynamic performance, system inductance and overall solution ON resistance. Package parasitics and problematical layouts associated with conventional discrete solutions are greatly reduced. This integrated approach results in significant board space saving, therefore maximizing footprint power density. This solution is based on the Intel™ DrMOS specification.
