Description

The APW3007 provides the power control and protection for four output voltage in high-performance microprocessor and computer applications.
The APW3007 is designed to provide termination voltage VTT(1.25V) with ±1% accuracy. It integrates two PWM controllers , a linear regulator and a liear controller as well as the monitoring and protection function into a single package. One PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter , while the second PWM controller supplies the I/O 3.3V power with a standard buck converter. The linear controller regulates power for GTL bus and the intermal 200mA regulator for clock driver circuits.
The APW3007 can provide in excess of 14A of output current for an on-board DC/DC converter via internal reference voltage. It can monitor all the output voltage , and a single Power Good signal is issued when the core is within 10% of the internal reference voltage and the other levels are above their undervoltage levels. Additional built-in over-voltage protection for the core output uses the lower MOSFET to prevent output voltage above 115% of the reference voltage. The PWM controller's over-current function monitor the output current by sensing the voltage drop across the upper MOSFET's RDS(ON) , eliminating the need for a current sensing resistor.
