FDQ7698S
Dual Notebook Power Supply N-Channel PowerTrench in SO-14 Package
General Description
The FDQ7698S 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: 15 A, 30V. R_DS(on) = 7.5 mΩ @ V_GS = 10V
R_DS(on) = 9 mΩ @ V_GS = 4.5V
• Q1: 12A, 30V. R_DS(on) = 12 mΩ @ V_GS = 10V
R_DS(on) = 16 mΩ @ V_GS = 4.5V
