FDQ7238AS
Dual Notebook Power Supply N-Channel PowerTrench® in SO-14 Package
General Description
The FDQ7238AS is designed to replace two single SO8 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. The FDQ7238AS includes a patented combination of a MOSFET monolithically integrated with a
Schottky diode.
Features
Q2: 14 A, 30V. RDS(on) = 8.7 mΩ @ VGS = 10V RDS(on) = 10.5 mΩ @ VGS = 4.5V
Q1: 11 A, 30V. RDS(on) = 13.2 mΩ @ VGS = 10V RDS(on) = 16 mΩ @ VGS = 4.5V
