Fairchild FDS6982 Dual n-channel, notebook power supply mosfet Datasheet

FDS6982
Dual N-Channel, Notebook Power Supply MOSFET
General Description
Features
This part is designed to replace two single SO-8 MOSFETs
in synchronous DC:DC power supplies that provide the
various peripheral voltage rails required in notebook
computers and other battery powered electronic devices.
FDS6982 contains two unique 30V, N-channel, logic level,
PowerTrenchTM MOSFETs designed to maximize power
conversion efficiency.
•
The high-side switch (Q1) is designed with specific
emphasis on reducing switching losses while the low-side
switch (Q2) is optimized for low conduction (less than 20mΩ
at VGS = 4.5V).
Applications
• Battery powered synchronous DC:DC converters.
• Embedded DC:DC conversion.
Q2: 8.6A, 30V. RDS(on) = 0.015 Ω @ VGS = 10V
RDS(on) = 0.020 Ω @ VGS = 4.5V
•
Q1: 6.3A, 30V. RDS(on) = 0.028 Ω @ VGS = 10V
RDS(on) = 0.035 Ω @ VGS = 4.5V
•
Fast switching speed.
•
Low gate charge (Q1 typical = 8.5nC).
•
High performance trench technology for extremely
low RDS(ON).
