RT9230 - 1.5V Advanced Dual PWM and Dual Linear Power Controller

Description

The RT9230 is a 4-in-one power controller optimized for high-performance microprocessor and computer applications.

The IC integrates two PWM controller, two linear controllers as well as monitoring and protection functions into a 28-pin SOP package.

Features

  • an Intel-compatible, TTL 5-bit programmable DAC that adjusts the core voltage from 2.1V to 3.5V in 0.1V increments and from 1.3V to 2.05V in 0.05V steps. The 5-bit DAC has a typical ±1% tolerance. The second PWM controller is usersel.

RT9230 1.5V Advanced Dual PWM and Dual Linear Power Controller General Description The RT9230 is a 4-in-one power controller optimized for high-performance microprocessor and computer applications. The IC integrates two PWM controller, two linear controllers as well as monitoring and protection functions into a 28-pin SOP package. The first PWM controller regulates the microprocessor core voltage with a synchronous buck converter, while the second PWM controller supplies the computer system’s AGP 1.5V or 3.3V bus power with a standard buck converter. The first linear regulator provides power for the 1.5V GTL bus and the second linear regulator provides 1.8V power for the North/South Bridge core voltage and/or cache memory circuits.
