Integrated Driver and MOSFET with Integrated Current Monitor NCP303150D Description The NCP303150D integrates a MOSFET driver, high side www.onsemi.com MOSFET and lowside MOSFET into a single package. The driver and MOSFETs have been optimized for highcurrent DCDC buck power conversion applications. The NCP303150D integrated solution greatly reduces package parasitics and board space compared to a discrete component solution. Features Capable of Average Currents up to 50 A 30 V / 30 V Breakdown Voltage MOSFETs for Higher Long Term PQFN39 Reliability MN SUFFIX CASE 483BF HighPerformance, Universal Footprint, CopperClip 5 mm x 6 mm PQFN Package Capable of Switching at Frequencies up to 1 MHz MARKING DIAGRAM Compatible with 3.3 V or 5 V PWM Input Responds Properly to 3level PWM Inputs Precise Current Monitoring NCP 303150D Option for Zero Cross Detection with 3level PWM AZZYYWW Internal Bootstrap Diode Catastrophic Fault Detection Thermal Flag (OTP) for OverTemperature Condition NCP303150D = Specific Device Code OverCurrent Protection FAULT (OCP) A = Assembly Location UnderVoltage Lockout (UVLO) on VCC and PVCC ZZ = Wafer Lot Supports Intel Power State 4 YY = Year WW = Work Week Applications Desktop & Notebook Microprocessors ORDERING INFORMATION Graphic Cards Routers and Switches Device Package Shipping NCP303150DMNTWG PQFN39 3000 / Tape & (PbFree) Reel For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D.
