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
Schottky. SyncFET^TM technology reduces this
inductance to a minimum by providing a monolithic
solution (MOSFET and Schottky in the same die),
resulting in optimum performance.
Applications
• Synchronous Rectifier
• Features
• 16 A, 30 V
R_DS(ON) = 8.0 mΩ @ V_GS = 10 V
R_DS(ON) = 9.5 mΩ @ V_GS = 4.5 V
