5-BIT PROGRAMMABLE SYNCHRONOUS BUCK PLUS TRIPLE LDO CONTROLLER DESCRIPTION
The IRU3021M controller IC is specifically designed to meet Intel specification for next generation microprocessor applications requiring multiple on-board regulators. The IRU3021M provides a single chip controller IC for the Vcore, three LDO controllers, one with an automatic select pin that connects to the Type Detect pin of the AGP slot for the AGP VDDQ supply, one for GTL+ and the other for the 1.8V chip set regulator as required for the next generation PC applications. The IRU3021M uses N-channel MOSFET as pass transistor for Vout2(VDDQ), Vout3(1.5V) and Vout4(1.8V). No external...
