IRU3011
5-BIT PROGRAMMABLE SYNCHRONOUS BUCK
CONTROLLER IC
FEATURES
Dual Layout compatible with HIP6004A
Designed to meet Intel specification of VRM8.4 for
Pentium III ?
On-Board DAC programs the output voltage from
1.3V to 3.5V. The IRU3011 remains on for VID code
of (11111).
Loss-less Short Circuit Protection
Synchronous operation allows maximum efficiency
Patented architecture allows fixed frequency
operation as well as 100% duty cycle during
dynamic load
Over-Voltage Protection Output
Soft-Start
High current totem pole driver for direct driving of the
external power MOSFET
Power Good Function
APPLICATIONS
Pentium III & Pentium II ? processor DC to DC
converter application
Low Cost Pentium with AGP
TYPICAL APPLICATION
DESCRIPTION
The IRU3011 controller IC is specifically designed to meet
Intel specification for latest Pentium III ? microproces-
sor applications as well as the next generation P6 fam-
ily processors. These products feature a patented topol-
ogy 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. These devices also
features, loss less current sensing by using the R DS(ON)
of the high side Power MOSFET as the sensing resis-
tor, a Power Good window comparator that switches its
open collector output low when the output is outside of a
± 10% window and an Over-Voltage Protection output.
Other features of the device are: Under-voltage lockout
for both 5V and 12V supplies, an external programmable
soft-start function as well as programming the oscillator
frequency by using an external capacitor.
Note: Pentium II and Pentium III are trade marks of Intel Corp.
