IRU3011  
5-BIT PROGRAMMABLE SYNCHRONOUS BUCK  
CONTROLLER IC  
FEATURES  
DESCRIPTION  
The IRU3011 controller IC is specifically designed to meet  
Dual Layout compatible with HIP6004A  
Designed to meet Intel specification of VRM8.4 for Intel specification for latest Pentium IIIä microproces-  
Pentium IIIä sor applications as well as the next generation P6 fam-  
On-Board DAC programs the output voltage from ily processors. These products feature a patented topol-  
1.3V to 3.5V. The IRU3011 remains on for VID code ogy that in combination with a few external components  
of (11111).  
Loss-less Short Circuit Protection  
as shown in the typical application circuit,will provide in  
excess of 20A of output current for an on-board DC/DC  
Synchronous operation allows maximum efficiency converter while automatically providing the right output  
Patented architecture allows fixed frequency  
operation as well as 100% duty cycle during  
dynamic load  
Over-Voltage Protection Output  
Soft-Start  
voltage via the 5-bit internal DAC. These devices also  
features, loss less current sensing by using the RDS(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  
High current totem pole driver for direct driving of the ±10% window and an Over-Voltage Protection output.  
external power MOSFET  
Power Good Function  
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.  
APPLICATIONS  
Pentium III & Pentium IIä processor DC to DC  
converter application  
Low Cost Pentium with AGP
