Advanced Dual PWM and Dual Linear

Power Control

Features

• Provides 4 Regulated Voltages

The HIP6019 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.

- Microprocessor Core, I/O, Clock Chip and GTL Bus

• Drives N-Channel MOSFETs

• Operates from +5V and +12V Inputs

• Simple Single-Loop Control Designs

- Voltage-Mode PWM Control

• Fast Transient Response

- High-Bandwidth Error Ampliﬁers

- Full 0% to 100% Duty Ratios

• Excellent Output Voltage Regulation

The HIP6019 includes an Intel-compatible, TTL 5-input digital-

to-analog converter (DAC) that adjusts the core PWM output

- I/O PWM Output: ±2% Over Temperature

- Other Outputs: ±2.5% Over Temperature

to 3.5V

in 0.1V increments and from

in 0.05V steps. The precision reference

1.8V

to 2.05V

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 HIP6019 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
