Advanced Dual PWM and Dual Linear

Power Control

Features

• Provides 4 Regulated Voltages

The HIP6019B provides the power control and protection for

four output voltages in high-performance microprocessor and

computer applications. The IC integrates two PWM

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

• Drives N-Channel MOSFETs

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.

• 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 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%.

- Core PWM Output: ±1% Over Temperature

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

- Other Outputs: ±2.5% Over Temperature

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

• Power-Good Output Voltage Monitor

• Microprocessor Core Voltage Protection Against Shorted

• Over-Voltage and Over-Current Fault Monitors

- Does Not Require Extra Current Sensing Element,

controller’s over-current functions monitor the output current

by sensing the voltage drop across the upper MOSFET’s
