FET socket of Sync. Buck Converter l Low Conduction and Switching Losses l Compatible with existing Surface Mount Techniques l 100% Rg tested PD - 97433B Description The IRF6798MPbF combines the latest HEXFET® Power MOSFET Silicon technology with the advanced DirectFETTM packaging to achieve the lowest on-state resistance in a package that has the footprint of a SO-8 and only 0.7 mm profile. The DirectFET package is compatible with existing layout geometries used in power applications, PCB assembly equipment and vapor phase, infra-red or convection soldering techniques. Application note AN-1035 is followed regarding the manufacturing methods and processes. The DirectFET package allows dual sided cooling to maximize thermal transfer in power systems, improving previous best thermal resistance by 80%. The IRF6798MPbF balances industry leading on-state resistance while minimizing gate charge along with low gate resistance to reduce both conduction and switching losses. This part contains an integrated Schottky diode to reduce the Qrr of the body drain diode further reducing the losses in a Synchronous Buck circuit. The reduced losses make this product ideal for high frequency/high efficiency DC-DC converters that power high current loads such as the latest generation of microprocessors. The IRF6798MPbF has been optimized for parameters that are critical in synchronous buck converter’s Sync FET sockets. 2 4 6 8 10 12 14 16 18 20 VGS, Gate -to -Source Voltage (V) 0 1 2 3 4 5 ID = 37A TJ = 25°C TJ = 125°C 0 25 50 75 100 125 150 QG Total Gate Charge (nC) 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 VDS= 20V VDS= 13V ID= 30A Qg tot Qgd Qgs2 Qrr Qoss Vgs(th) 50nC 16nC 6.8nC 64nC 38nC 1.8V Absolute Maximum Ratings Parameter Units VDS Drain-to-Source Voltage V VGS Gate-to-Source Voltage ID @ TA = 25°C Continuous Drain Current, VGS @ 10V e ID @ TA = 70°C Continuous Drain Current, VGS @ 10V e A ID @ TC = 25°C Continuous Drain Current, VGS @ 10V f IDM Pulsed Drain Current g EAS Single Pulse Avalanche Energy h mJ IAR Avalanche Current Ãg A 30 Max. 30 197 300 ±20 25 37 220 VDSS VGS RDS(on) RDS(on) 25V max ±20V max 0.95mΩ@ 10V 1.6mΩ@ 4.5V |
