HIP6028 Datasheet Advanced Pwm And Dual Linear Power Control With Integrated ACpi Support Interface

Manufacturer: Intersil (now Renesas)

Overview: HIP6028 Data Sheet May 1998 File Number 4630 Advanced PWM and Dual Linear Power Control with Integrated ACPI Support Interface The HIP6028 provides the power control and protection for three output voltages in high-performance microprocessor and puter 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 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 circuit. The HIP6028 includes an Intel-patible, 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 1.3VDC 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 a fixed 2.5V ±2.5%. The linear controller drives an external N-channel MOSFET to provide a fixed 1.5V ±2.5%. The HIP6028 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), eliminating the need for a current sensing resistor. The HIP6028 offers integrated ACPI S3 shutdown state support. Through the SD1&3 pin, the microprocessor core and GTL bus supplies can be shut down when entering power-saving standby operation mode.
