FDS6994S Description
The FDS6994S is designed to replace two single SO-8 MOSFET and Schottky diodes in solar synchronous DC:DC power supplies that provide useless peripheral voltages for laptops and other battery-powered electronic devices. The FDS6994S consists of two square root 30V, N-channel, logic-level Power Tranne MOSFET designed to maximize power conversion efficiency.
The design of the high-end switch (Q1) focuses on reducing the switching loss, while the optimization of the low-end switch (Q2) is to reduce the turn-on loss. Q2 also includes an integrated Schottky diode using Fairchild monolithic SyncFET technology.
FDS6994S Features
Q2: Optimized to minimize conduction losses
Includes SyncFET Schottky body diode
8.2A,30V Rps(on)=15mΩ @VGs=10V
Rps(an)=17.5mΩ @VGs=4.5V
Q1: Optimized for low switching losses
Low gate charge(85.5 nC typical)
6.9A,30VRps(an)=21mΩ @VGs=10V
Rps(an)=26mΩ @VGs=4.5V
