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.  
Q2: 8.6A, 30V. RDS(on) = 0.015 @ VGS = 10V  
RDS(on) = 0.020 @ VGS = 4.5V  
Q1: 6.3A, 30V. RDS(on) = 0.028 @ VGS = 10V  
RDS(on) = 0.035 @ VGS = 4.5V  
Fast switching speed.  
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  
Low gate charge (Q1 typical = 8.5nC).  
High performance trench technology for extremely  
at VGS = 4.5V).  
low RDS(ON)  
.
Applications  
Battery powered synchronous DC:DC converters.  
Embedded DC:DC conversion.
