May 2004

FDD6688S
30V N-Channel PowerTrench SyncFETTM
General Description
The FDD6688S is designed to replace a single TO-252 MOSFET and Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDD6688S includes an integrated Schottky diode using Fairchild's monolithic SyncFET technology. Applications · DC/DC converter · Motor Drives

Features
· 88 A, 30 V. RDS(ON) = 5.1 m @ VGS = 10 V RDS(ON) = 6.3 m @ VGS = 4.5 V · Low gate charge (31 nC typical) · Fast switching · High performance trench technology for extremely low RDS(ON)

Drain­Source Diode Characteristics and Maximum Ratings

diF/dt = 300 A/µs

Notes:8 1. RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RJC is guaranteed by design while RCA is determined by the user's board design.

a) RJA = 40°C/W when mounted on a
2 1in pad of 2 oz copper

b) RJA = 96°C/W when mounted on a minimum pad.

Scale 1 : 1 on letter size paper 2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0% 3. Maximum current is calculated as:
PD R DS(ON)

where PD is maximum power dissipation at TC = 25°C and RDS(on) is at TJ(max) and VGS = 10V. Package current limitation is 21A
