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 FDMF5826DC integrates a driver IC with a bootstrap Schottky diode, two power MOSFETs, and a thermal monitor 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 RDS(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. A thermal monitor function warns of a potential over-temperature situation. The FDMF5826DC incorporates an Auto-DCM Mode (ZCD#) for improved light-load efficiency. The FDMF5826DC also provides a 3-state 5 V PWM input for compatibility with a wide range of PWM controllers.
