Data Sheet No. PD94144  
IRU3018  
5-BIT PROGRAMMABLE SYNCHRONOUS BUCK PLUS  
LDO CONTROLLER AND 200mA LDO ON-BOARD  
FEATURES  
DESCRIPTION  
Provides single chip solution for Vcore, GTL+ & clock The IRU3018 controller IC is specifically designed to meet  
supply  
Intel specification for Pentium II microprocessor appli-  
cations as well as the next generation of P6 family pro-  
200mA On-Board LDO Regulator  
Designed to meet the latest Intel specification for cessors. The IRU3018 provides a single chip controller  
Pentium II  
On-Board DAC programs the output voltage from 200mA regulator for clock supply which are required for  
1.3V to 3.5V the Pentium II applications. These devices feature a pat-  
IC for the Vcore, LDO controller for GTL+ and an internal  
Linear regulator controller on board for 1.5V GTL+ ented topology that in combination with a few external  
supply  
components as shown in the typical application circuit,  
will provide in excess of 18A of output current for an on-  
Loss-less Short Circuit Protection with HICCUP  
Synchronous operation allows maximum efficiency board DC-DC converter while automatically providing the  
patented architecture allows fixed frequency opera- right output voltage via the 5-bit internal DAC. The  
tion as well as 100% duty cycle during dynamic IRU3018 also features loss-less current sensing for both  
load  
switchers by using the RDS(on) of the high-side power  
MOSFET as the sensing resistor, internal current limit-  
Soft-Start  
High current totem pole driver for direct driving of the ing for the clock supply, and a Power Good window com-  
external power MOSFET  
parator that switches its open collector output low when  
any one of the outputs is outside of a pre-programmed  
Power Good Function monitors all outputs  
Over-Voltage Protection circuitry protects the window. Other features of the device are: Under-voltage  
switcher output and generates a fault signal  
Thermal Shutdown  
lockout for both 5V and 12V supplies, an external pro-  
grammable soft-start function, programming the oscilla-  
tor frequency via an external resistor, Over-Voltage Pro-  
tection (OVP) circuitry for both switcher outputs and an  
internal thermal shutdown.
