FDS7064SN3 - 30V N-Channel PowerTrench SyncFET

General Description

The FDS7064SN3 is designed to improve the efficiency of Buck Regulators.

Used as the Synchronous rectifier, (Low side MOSFET), losses can be reduced, not only in this device, but also in the Control switch, (High side MOSFET).

Key Features

  • DS(ON) = 8.0 mΩ @ VGS = 10 V RDS(ON) = 9.5 mΩ @ VGS = 4.5 V.
  • 16 A, 30 V.
  • High performance trench technology for extremely low RDS(ON).
  • No inductance between MOSFET and Schottky.
  • 40% reduction in Body Diode Forward Voltage.
  • Optimized to reduce losses in Synchronous Buck Regulators.
  • FLMP SO-8 package for enhanced thermal performance.

FDS7064SN3 February 2004 FDS7064SN3 30V N-Channel PowerTrench SyncFET™ General Description The FDS7064SN3 is designed to improve the efficiency of Buck Regulators. Used as the Synchronous rectifier, (Low side MOSFET), losses can be reduced, not only in this device, but also in the Control switch, (High side MOSFET). After the low side MOSFET turns off, reverse recovery current in the body diode is dissipated in the High Side device. A Discrete Schottky diode in parallel with the Low Side MOSFET can lower the reverse recovery current, but parasitic PCB and Package Inductance reduce the effectiveness of the TM technology reduces this Schottky. SyncFET inductance to a minimum by providing a monolithic solution (MOSFET and Schottky in the same die), resulting in optimum performance.
