PRELIMINARY

Advanced PWM and Dual Linear Power

Control

Features

• Provides 3 Regulated Voltages

The HIP6017B provides the power control and protection for

three output voltages in high-performance microprocessor

and computer applications. The IC integrates a PWM

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

the monitoring and protection functions into a single 28 lead

SOIC 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 circuits.

- Microprocessor Core, Clock and GTL Power

• Linear Controller Drives Either N-Channel MOSFETs or

Bipolar Transistors

• 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 HIP6017B 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

Voltage Selection

- Wide Range - 1.3V

to 3.5V

- 0.1V Steps from 2.1V

to 3.5V

- 0.05V Steps from 1.3V

The HIP6017B 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

to 2.05V

• Power-Good Output Voltage Monitor

• Microprocessor Core Voltage Protection Against Shorted

MOSFET

• Over-Voltage and Over-Current Fault Monitors

- Does Not Require Extra Current Sensing Element,

voltage drop across the upper MOSFET’s r

DS(ON)

Uses MOSFET’s r

DS(ON)

eliminating the need for a current sensing resistor.

• Small Converter Size

- Constant Frequency Operation

- 200kHz Free-Running Oscillator; Programmable from

50kHz to over 1MHz
