Advanced PWM and Dual Linear Power

Control

Features

• Provides 3 Regulated Voltages

The HIP6018B provides the power control and protection for

three output voltages in high-performance microprocessor

and computer applications. The IC integrates a PWM

controllers, 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.

- Microprocessor Core, Clock and GTL Power

• Drives N-Channel MOSFETs

• Operates from +3.3V, +5V and +12V Inputs

• Simple Single-Loop PWM Control Design

- Voltage-Mode Control

• Fast Transient Response

- High-Bandwidth Error Ampliﬁer

- Full 0% to 100% Duty Ratios

The HIP6018B 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 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%.

• Excellent Output Voltage Regulation

- Core PWM Output: ±1% Over Temperature

- Other Outputs: ±2.5% Over Temperature

• TTL-Compatible 5-Bit Digital-to-Analog Core Output

The HIP6018B 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 over-

current function monitors the output current by using the
