APW3007
Advanced Dual Dual Linear Power Controller
Provides Regulated Voltages
General Description
APW3007 provides power control protection four output voltage high-performance microprocessor computer applications. APW3007 designed provide termination voltage VTT(1.25V) with accuracy. integrates controllers linear regulator liear controller well monitoring protection function into single package. controller regulates microprocessor core voltage with synchronous-rectified buck converter while second controller supplies 3.3V power with standard buck converter. linear controller regulates power intermal 200mA regulator clock driver circuits. APW3007 provide excess output current on-board DC/DC converter internal reference voltage. monitor output voltage single Power Good signal issued when core within internal reference voltage other levels above their undervoltage levels. Additional built-in over-voltage protection core output uses lower MOSFET prevent output voltage above 115% reference voltage. controller's over-current function monitor output current sensing voltage drop across upper MOSFET's RDS(ON) eliminating need current sensing resistor.
