FDQ7244S
Dual Notebook Power Supply N-Channel PowerTrench in SO-14 Package
General Description
The FDQ7244S is designed to replace two single SO-8
MOSFETs in DC to DC power supplies. The high-side
switch (Q1) is designed with specific emphasis on
reducing switching losses while the low-side switch
(Q2) is optimized to reduce conduction losses using
Fairchild’s SyncFET TM technology.
Features
• Q2: 14 A, 30V. RDS(on) = 9.5 mΩ @ VGS = 10V
RDS(on) = 10.5 mΩ @ VGS = 4.5V
• Q1: 11 A, 30V. RDS(on) = 14.5 mΩ @ VGS = 10V
RDS(on) = 16 mΩ @ VGS = 4.5V
