Integrated Driver & MOSFET | FDMF3030

The DrMOS family is Fairchild’s next-generation, fully optimized, ultra-compact, integrated MOSFET -plus -driver, power-stage solution for high-current, high-frequency, synchronous buck, DC-DC applications. The FDMF3030 integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact, 6x6mm package.
With an integrated approach, the complete switching power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET R_DS(ON). The FDMF3030 uses Fairchild's high-performance PowerTrench^® MOSFET technology, which dramatically reduces switch ringing, eliminating the need for a snubber circuit in most buck converter applications.
A driver IC with reduced dead times and propagation delays further enhances performance. A thermal warning function indicates a potential over-temperature situation. The FDMF3030 also incorporates a Zero-Cross Detect (ZCD_EN# pin) for improved light-load efficiency and provides a 3-state 5V PWM input for compatibility with a wide range of PWM controllers.
