Overview

1 Advanced PWM and Dual Linear Power Control The HIP6017 provides the power control and protection for three output voltages in high-performance microprocessor and computer applications.
The IC integrates a PWM controller, a linear regulator and a linear controller as well as the monitoring and protection functions into a single 28 lead SOIC package.
The PWM controller regulates the microprocessor core voltage with a synchronous-rectified buck converter.
The linear controller regulates power for the GTL bus and the linear regulator provides power for the clock driver circuits.
The HIP6017 includes an Intel-compatible, TTL 5-input digital-to-analog converter (DAC) that adjusts the core PWM output voltage from 2.
1VDC to 3.
5VDC in 0.
1V increments and from 1.
8VDC to 2.
05VDC in 0.
05V steps.
The precision reference and voltage-mode control provide ±1% static regulation.
The linear regulator uses an internal pass device to provide 2.
5V ±2.
5%.
The linear controller drives an external N-Channel MOSFET to provide 1.
5V ±2.
5%.
The HIP6017 monitors all the output voltages.
A single Power Good signal is issued when the core is within ±10% of the DAC setting 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 voltages above 115% of the DAC setting.
The PWM overcurrent function monitors the output current by using the voltage drop across the upper MOSFET’s rDS(ON), thus eliminating the need for a current sensing resistor.
