onsemi FDMF6706B

The FDMF6706B is an integrated DrMOS power stage module designed for high-current, high-frequency synchronous buck DC-DC converters. It combines a driver IC, two PowerTrench® MOSFETs, and an integrated bootstrap Schottky diode in a 40-lead, 6.0 mm × 6.0 mm PQFN package with copper-clip technology. The module supports switching frequencies up to 1 MHz and handles a continuous output current of 45 A at 12 V input under natural convection cooling. It features a three-state 3.3 V PWM input, adaptive gate drive timing for shoot-through protection, skip-mode operation for improved light-load efficiency, thermal warning flag output, and under-voltage lockout. The device complies with the Intel® DrMOS 4.0 standard and is RoHS compliant. Thermal resistance from junction to PCB is 3.5 °C/W and maximum junction temperature is 150 °C.
