VRM 8.5 COMPATIBLE 5-BIT PROGRAMMABLE SYNCHRONOUS BUCK CONTROLLER IC

Data Sheet No. PD94249 IRU3013 VRM 8.5 COMPATIBLE 5-BIT PROGRAMMABLE SYNCHRONOUS BUCK CONTROLLER IC WITH TRIPLE LDO CONTROLLER FEATURES Meets Latest VRM 8.5 Specification Provides Single Chip Solution for Vcore, 1.2V AGTL+, 1.8V and VDDQ On-Board 5-Bit DAC and Decoder programs the output voltage from 1.050V to 1.825V Loss-less Short Circuit Protection Synchronous operation allows maximum efficiency Patented architecture allows fixed frequency operation as well as 100% duty cycle when operating with a changing load Minimum Part Count, No External Compensation Soft-Start High current totem pole driver for directly driving an external Power MOSFET Power Good Function APPLICATIONS Pentium III with VRM 8.5 Specification DC to DC Converters 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 uncommitted 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. The IRU3013 features a patented topology that, in combination with a few external components, (*Note: See application current in Figure 3) will provide in excess of 30A of output current for an onboard Vcore synchronous converter while automatically providing the output voltage specified in VRM 8.5 specification. The IRU3013 also features, loss-less current.
