IRU3013 Datasheet Vrm 8.5 Compatible 5-bit Programmable Synchronous Buck Controller Ic

Manufacturer: International Rectifier (now Infineon)

Overview: Data Sheet No. PD94249 IRU3013 VRM 8.5 PATIBLE 5-BIT PROGRAMMABLE SYNCHRONOUS BUCK CONTROLLER IC WITH TRIPLE LDO.

General Description

The IRU3013 controller IC is specifically designed for Intel Pentium III™ microprocessor applications as described in the VRM 8.5 specification.

The IC provides a single chip solution for the Vcore, 1.2V AGTL+, 1.8V and a third unmitted LDO controller that can be used either as 1.2V power good detector or to provide 1.5V AGP bus in applications that this voltage is required.
