Advanced PWM and Dual Linear Power

Control

Features

• Provides 3 Regulated Voltages

- Microprocessor Core, Clock and GTL Power

• Drives N-Channel MOSFETs

The HIP6018 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.

• 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

• Excellent Output Voltage Regulation

- Core PWM Output: ±1% Over Temperature

- Other Outputs: ±2.5% Over Temperature

The HIP6018 includes an Intel-compatible, TTL 5-input

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

output voltage from 2.1V

to 3.5V

in 0.1V increments

in 0.05V steps. The precision

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

Voltage Selection

to 2.05V

and from 1.8V

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%.

• Microprocessor Core Voltage Protection Against Shorted

MOSFET

The HIP6018 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

• Over-Voltage and Over-Current Fault Monitors

- Does Not Require Extra Current Sensing Element,

Uses MOSFET’s r

• Small Converter Size

- Constant Frequency Operation

voltage drop across the upper MOSFET’s r

eliminating the need for a current sensing resistor.
