FDS6982S Datasheet Dual N-channel MOSFET

Manufacturer: Fairchild (now onsemi)

Overview: FDS6982S March 2000 PRELIMINARY FDS6982S Dual Notebook Power Supply N-Channel PowerTrench.

General Description

The FDS6982S is designed to replace two single SO-8 MOSFETs and Schottky diode in synchronous DC:DC power supplies that provide various peripheral voltages for notebook puters and other battery powered electronic devices.

FDS6982S contains two unique 30V, N-channel, logic level, PowerTrench MOSFETs designed to maximize power conversion efficiency.

The high-side switch (Q1) is designed with specific emphasis on reducing switching losses while the lowside switch (Q2) is optimized to reduce conduction losses.

Key Features

  • Q2: Optimized to minimize conduction losses Includes SyncFET Schottky body diode RDS(on) = 0.016Ω @ VGS = 10V RDS(on) = 0.021Ω @ VGS = 4.5V.
  • Q1: Optimized for low switching losses Low Gate Charge ( 8.5 nC typical) RDS(on) = 0.028Ω @ VGS = 10V RDS(on) = 0.035Ω @ VGS = 4.5V 8.6A, 30V 6.3A, 30V D1 D1 D2 D2 S1 G1 5 6 7 Q1 4 3 2 Q2 SO-8 S2 8 1 G2 Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current TA = 25°C unless otherwi.
