General Description
APW6020 provides power control protection four output voltages high-performance graphics intensive microprocessor computer applications. integrates voltage-mode controllers linear controllers well monitoring protection functions into single package. controller regulates microprocessor core voltage with synchronous-rectified buck converter. second controller supplies computer's 1.5V 3.3V power with standard Buck converter. linear controllers requlate power 1.5V 1.8V power North/South Bridge core voltage and/or cache memory circuits. APW6020 includes Intel-compatible 5-input digital-toanalog converter (DAC) that adjusts core output voltage from 2.05 0.05V steps from 0.1V increments. precision reference voltage-mode control provide static regulation. second controller's output user-selectable through TTL-compatible signal applied SELECT levels 1.5V 3.3V with accuracy. linear regulators provide fixed output voltages 1.5V± (VOUT3 1.8V±3% (VOUT4 APW6020 monitors output voltages. single Power Good signal issued when core within ±10% setting other outputs above their under-voltage levels. Additional builtin over-voltage protection core output uses lower MOSFET prevent output voltages above 115% setting. controller's overcurrent function monitors output current using voltage drop across upper MOSFET's rDS(ON)
