IRU3007CW集成电路（IC）的特殊用途稳压器规格书PDF中文资料

DESCRIPTION

The IRU3007 controller IC is specifically designed to meet Intel specification for Pentium IIä microprocessor applications as well as the next generation of P6 family processors. The IRU3007 provides a single chip controller IC for the Vcore, LDO controller for GTL+ and an internal 200mA regulator for clock supply which are required for the Pentium II applications. It also contains a switching controller to convert 5V to 3.3V regulator for on-board applications that uses either AT type power supply or is desired not to rely on the ATX power supply’s 3.3V output.

FEATURES

■ Provides Single Chip Solution for Vcore, GTL+, Clock Supply & 3.3V Switcher On-Board

■ Second switcher provides simple control for the on-board 3.3V supply

■ 200mA On-Board LDO Regulator

■ Designed to meet Intel VRM 8.2 and 8.3 specification for Pentium IIä

■ On-Board DAC programs the output voltage from 1.3V to 3.5V

■ Linear Regulator Controller On-Board for 1.5V GTL+ supply

■ Loss-less Short Circuit Protection

■ Synchronous Operation allows maximum efficiency

■ Patented architecture allows fixed frequency operation as well as 100 duty cycle during dynamic load

■ Minimum Part Count
