Integrated Driver & MOSFET | FDMF301155

The SPS 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 FDMF301155 integrates a driver IC with a bootstrap Schottky diode and two power MOSFETs into a thermally enhanced, ultra-compact 5 mm x 5 mm package.
With an integrated approach, the SPS switching power stage is optimized for driver and MOSFET dynamic performance, minimized system inductance, and power MOSFET R_DS(ON). The SPS family uses Fairchild's high-performance PowerTrench® MOSFET technology, which 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 the performance. The FDMF301155 supports diode emulation (using FCCM pin) for improved light-load efficiency. The FDMF301155 also provides a 3-state 5 V PWM input for compatibility with a wide range of PWM controllers.
