Features General 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 1 15% 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 R
DS(ON)
, eliminating the
need for a current sensing resistor.
