16. FDC642

16.1. General Description

This P-Channel 2.5V specified MOSFET is produced using Fairchild's advanced
PowerTrench® process that has been especially tailored to minimize on-state resistance
and yet maintain low gate charge for superior switching performance.
These devices have been designed to offer exceptional power dissipation in a very small
footprint for applications where the larger packages are impractical.

16.2. Features

 Max rDS(on) = 65 mΩ at VGS = -4.5 V, ID = -4.0 A
 Max rDS(on) = 100 mΩ at VGS = -2.5 V, ID = -3.2 A
 Fast switching speed
 Low gate charge (11nC typical)
 High performance trench technology for extremely low rDS(on)
 SuperSOTTM-6 package: small footprint (72% smaller than standard SO-8);
low profile (1 mm thick)
 Termination is Lead-free and RoHS Compliant

than 900mV. When the voltage on EN exceeds 1.2V, the internal
regulator will be enabled and the soft-start capacitor will begin to
charge. The MP1583 will start switching after the EN pin voltage
reaches 2.71V.
SS Soft-Start Control Input. SS controls the soft-start period.
