General Description

The FDQ7238AS 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. 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
