The SPS family is ON Semiconductor’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 NCV3025833 integrates a driver IC with a bootstrap Schottky diode, two power MOSFETs, and a thermal monitor into a thermally enhanced, ultra-compact 5 mm × 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 ON Semiconductor’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 warning function warns of a potential over-temperature situation. A thermal shutdown function turns off the driver if an over-temperature condition occurs. The NCV3025833 incorporates an Auto-DCM Mode (ZCD#) for improved light-load efficiency.
The NCV3025833 also provides a 3-state 5 V PWM input for compatibility with a wide range of PWM controllers.
