HIP6018B provides power control protection three output voltages high-performance microprocessor computer applications. integrates controllers, linear regulator linear controller well monitoring protection functions into single package. controller regulates microprocessor core voltage with synchronous-rectified buck converter. linear controller regulates power linear regulator provides power clock driver circuit. HIP6018B includes Intel-compatible, 5-input digital-to-analog converter (DAC) that adjusts core output voltage from 2.1VDC 3.5VDC 0.1V increments from 1.3VDC 2.05VDC 0.05V steps. precision reference voltage-mode control provide static regulation. linear regulator uses internal pass device provide 2.5V ±2.5%. linear controller drives external N-channel MOSFET provide 1.5V ±2.5%. HIP6018B monitors output voltages. single Power Good signal issued when core within ±10% setting other levels above their undervoltage levels. Additional built-in over-voltage protection core output uses lower MOSFET prevent output voltages above 115% setting. overcurrent function monitors output current using voltage drop across upper MOSFET's rDS(ON) eliminating need current sensing resistor.
