Advanced Dual PWM and Dual Linear

Power Control

The HIP6019B provides the power control and protection for

four output voltages in high-performance microprocessor and

computer applications. The IC integrates two PWM

controllers, a linear regulator and a linear controller as well as

the monitoring and protection functions into a single 28 lead

SOIC package. One PWM controller regulates the

microprocessor core voltage with a synchronous-rectified

buck converter, while the second PWM controller supplies the

computer’s 3.3V power with a standard buck converter. The

linear controller regulates power for the GTL bus and the

linear regulator provides power for the clock driver circuits.

The HIP6019B 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 1.3VDC to 2.05VDC in 0.05V steps. The precision

reference and voltage-mode control provide ±1% static

regulation. The second PWM controller is user-adjustable for

output levels between 3.0V and 3.5V with ±2% accuracy. The

adjustable linear regulator uses an internal pass device to

provide 2.5V ±2.5%. The adjustable linear controller drives an

external N-Channel MOSFET to provide 1.5V ±2.5%.

The HIP6019B 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 under-

voltage 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

controller’s over-current functions monitor the output current

by sensing the voltage drop across the upper MOSFET’s

, eliminating the need for a current sensing resistor.
