A Voltage Regulator Module (VRM) Using the
HIP6004 PWM Controller (HIP6004EVAL1)
Application Note

Author: Greg J. Miller
Introduction
Today’s high-performance microprocessors present many
challenges to their power source. High power consumption,
low bus voltages, and fast load changes are the principal
characteristics which have led to the need for a switch-mode
DC-DC converter local to the microprocessor.
Intel has specified a Voltage Regulator Module (VRM) for
the Pentium Pro Microprocessor [1]. This specification
details the requirements imposed upon the input power
source(s) by the Pentium-Pro and provides the computer
industry with a standard DC-DC converter solution. The
Intersil HIP6002 and HIP6003 pulse-width modulator (PWM)
controllers are targeted specifically for DC-DC converters
powering the Pentium-Pro and similar high-performance
microprocessors. The HIP6004 and HIP6005 PWM
controllers are enhanced versions of the HIP6002 and
HIP6003, with additional features specifically for next-
generation microprocessors.
Intersil HIP6004
Figure 1 shows a simple block diagram of the HIP6004. The
HIP6004 is the controller for a synchronous-rectified Buck
converter. It contains a high-performance error amplifier, a
high-resolution 5-bit digital-to-analog converter (DAC), a
programmable free-running oscillator, and a pair of N-Channel
MOSFET drivers. A more complete description of the part can
be found in the HIP6004 Data Sheet [2]. The HIP6005 is very
similar to the HIP6004, but is targeted for standard buck
converters.
VRM. Intersil also offers a Pentium-Pro VRM evaluation
board, the HIP6003EVAL1 [3].
HIP6004EVAL1 Features
? Exceeds Intel Pentium-Pro VRM Specifications
- Form-Factor (3.1” x 1.5” x 1.1”)
- Efficiency
- Regulation
? Operates in +5V or +12V Input Systems
? 5-Bit DAC with ± 1% Accuracy
? Overvoltage Protection via SCR and Fuse
? Overcurrent Protection
Input Voltage Sources
The HIP6004EVAL1 VRM is able to run off either +5VDC or
+12VDC main power source. In either case, +12V is
required for the bias supply of the HIP6004. The
HIP6004EVAL1 is configured to accept a 5V source, as
shown in Figure 2. The three approaches for powering the
VRM from +12V are:
1. Increase +5V source to +12V (for lab evaluation).
2. Tie 12Vin pins to 5Vin pins (again, lab evaluation).
3. Move F1 fuse as shown in Figure 2 and apply +12Vin (for
system implementation).

HIP6004EVAL1 Reference Design
The HIP6004EVAL1 is an evaluation board which highlights
the operation of the HIP6004 in an expanded version of the
Pentium-Pro VRM. This evaluation board has greater
voltage adjustability (1.3V - 3.5V) and higher output current
capability (up to 14A) than the Intel-specified Pentium-Pro
output voltage programming is defined in the HIP6004 Data
Sheet.
The HIP6004EVAL1 is a solution for many different
microprocessors, both present and future. It is capable of
supplying greater than 14A of current and provide output
voltages from 1.3V to 3.5V.
