1 / 9 page  ©2008 Fairchild Semiconductor Corporation FDQ7238AS Rev A1(X) FDQ7238AS Dual Notebook Power Supply N-Channel PowerTrench ® in SO-14 Package 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. R DS(on) = 8.7 mΩ @ VGS = 10V R DS(on) = 10.5 mΩ @ VGS = 4.5V • Q1: 11 A, 30V. R DS(on) = 13.2 mΩ @ VGS = 10V R DS(on) = 16 mΩ @ VGS = 4.5V SO-14 G1 G2 Vin S2 S2 S2 Absolute Maximum Ratings T A = 25°C unless otherwise noted Symbol Parameter Q2 Q1 Units VDSS Drain-Source Voltage 30 30 V VGSS Gate-Source Voltage ±20 ±20 V 14 11 ID Drain Current - Continuous (Note 1a) - Pulsed 50 50 A 2.4 1.8 PD Power Dissipation for Single Operation (Note 1a & 1b) (Note 1c & 1d) 1.3 1.1 W TJ, TSTG Operating and Storage Junction Temperature Range −55 to +150 °C Thermal Characteristics Thermal Resistance, Junction-to-Ambient (Note 1a & 1b) 52 68 RθJA (Note 1c & 1d) 94 118 °C/W Package Marking and Ordering Information Device Marking Device Reel Size Tape width Quantity FDQ7238AS FDQ7238AS 13” 16mm 2500 units pin 1 May 2008 |
