SC1471 - Power Supply Controller

Description

The SC1471 PowerStep™ II controller is a high speed, high performance hysteretic mode PWM controller.

Teamed with the SC1405 Smart Driver™ , it powers advanced Intel® Pentium® III processors.

Features

  • extended Intel Mobile Voltage Positioning (IMVP) to increase battery life by reducing the voltage at the processor when it is heavily loaded. It directly supports Intel® SpeedStep™ processors for even longer battery life, including IMVP extensions. The SC1471 incorporates direct “deeper sleep” mode support, which eliminates an external multiplexer in many.
