TYPICAL APPLICATION
5V
DESCRIPTION
The IRU3004 controller IC is specifically designed to meet
Intel specifications for Pentium III
microprocessor
applications as well as the next generation P6 family
processors. The IC provides a single chip controller IC
for the Vcore, GTL+ and clock supplies required for the
Pentium III applications. The IRU3004 features a pat-
ented topology, that in combination with a few external
components as shown in the typical application circuit,
will provide in excess of 20A of output current for an on-
board DC-DC converter while automatically providing the
right output voltage via the 5-bit internal DAC meeting
the latest VRM specification. The IRU3004 also features
loss-less current sensing by using the R
DS(on)
of the high
side power MOSFET as the sensing resistor and a Power
Good window comparator that switches its open collec-
tor output low when the output is outside of a
±
10%
window. Other features of the device are: under-voltage
lockout for both 5V and 12V supplies, an external pro-
grammable soft-start function as well as programming
the oscillator frequency by using an external capacitor.
Meets latest VRM 8.4 specification for PentiumIII
Provides single chip solution for Vcore, GTL+ and
clock supply
On-Board DAC programs the output voltage from
1.3V to 3.5V. The IRU3004 remains on for VID code
of (11111)
Dual linear regulator controller on-board for 1.5V
GTL+ and 2.5V clock supplies
Loss-less Short Circuit Protection
Synchronous operation allows maximum efficiency
Patented architecture allows fixed frequency opera-
tion as well as 100% duty cycle during dynamic
load
Minimum Part Count, No External Compensation
Soft-Start Function
High current totem pole driver for direct driving of the
external power MOSFET
Power Good Function
APPLICATIONS
Pentium III & next generation processor DC to DC
converter application
Low Cost Pentium with AGP
