DATA SHEET www.onsemi.com Single-Phase Voltage Regulator MARKING DIAGRAM High Efficiency, Integrated Power MOSFETs NCP3284, NCP3284A The NCP3284/A, a single−phase synchronous buck regulator, integrates power MOSFETs to provide a high−efficiency and compact−footprint power management solution. The NCP3284 is able to deliver up to 30 A TDC output current, 35 A TDC for NCP3284A, over a wide input and output operating voltage range. Operating in high switching frequency up to 1 MHz allows employing small size inductors and capacitors while maintaining high efficiency due to integrated solution with high performance power MOSFETs. It provides differential voltage sense, flexible soft−start programming, and comprehensive protections. Features • VIN = 4.
