Integrated Driver & MOSFET | NCV3025833
概览
The SPS family is onsemi’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 onsemi’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.
