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 FDMF5823DC 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. A programmable thermal shutdown function turns off the driver if an over-temperature condition occurs. The FDMF5823DC incorporates an Auto-DCM Mode (ZCD#) for improved light-load efficiency. The FDMF5823DC also provides a 3-state 3.3 V PWM input for compatibility with a wide range of PWM controllers.
