FDMF6730

FDMF6730 Driver plus FET Multi-chip Module August 2008 FDMF6730 Driver plus FET Multi-chip Module Features Over 95% efficiency Internal 5V regulator for gate drive 6V-16V input range 1MHz max operating frequency SMOD operation capability for light load efficiency 5A current capability (10A with PASS FET) Current limit set by RDSON sensing to minimize power losses Integrated bootstrap diode General Description The FDMF6730 is a high efficiency Driver plus MOSFET power stage solution optimized for Ultra Mobile PC (UMPC) system power voltage supplies. It is fully compliant with the Intel UltraMobile Driver MOS (uDrMOS) Specification. The MOSFETs and driver have been optimized to perform with high efficiency at light and medium loads, ideal for compact PC devices. The internal driver IC integrates two highly efficient LDOs for internal gate-drive and external circuitry. The bootstrap diode is also integrated within the IC. When operating with a single low side MOSFET the uDrMOS module is capable of delivering up to 5A of continuous current. The PASS transistor may be easily routed in parallel with the low side MOSFET to provide up to 10A. The module also incorporates an over current protection flag from an RDSON current sense architecture. The device comes in a 6X6 Power QFN package for improved thermal performance.
