FDP6690S/FDB6690S
30V N-Channel PowerTrench® SyncFET ™
General Description
This MOSFET is designed to replace a single MOSFET and parallel Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDP6690S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDP6690S/FDB6690S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDP6035AL/FDB6035AL in parallel with a Schottky diode.
Features
• 21 A, 30 V. RDS(ON) = 15.5 mΩ @ VGS = 10 V RDS(ON) = 23.0 mΩ @ VGS = 4.5 V • Includes SyncFET Schottky body diode • Low gate charge (11nC typical) • High performance trench technology for extremely low RDS(ON) and fast switching • High power and current handling capability

SyncFET Schottky Body Diode Characteristics
Fairchild’s SyncFET process embeds a Schottky diode in parallel with PowerTrench MOSFET. This diode exhibits similar characteristics to a discrete external Schottky diode in parallel with a MOSFET. Figure 12 FDP6690S. Schottky barrier diodes exhibit significant leakage at high temperature and high reverse voltage. This will increase the power in the device.
