SC451 - Single Phase Power Supply Controller

This page provides the datasheet information for the SC451, a member of the SC451ITSTRT Single Phase Power Supply Controller family.

Description

The SC451 PowerStep IV™ IC is a single chip high-performance Hysteretic PWM controller.

With its integrated SmartDriver™, it powers advanced IMVP-IV™ and IMVP4+™ 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’s SpeedStep® processors for even longer battery life. The SC451 fully supports the Intel® Geyserville-III core voltage specification. It provides direct “deeper sleep” mode and boot voltage support. Automatic “power-save” is present to prevent negative current flow in the low-side FET during light loading conditions, saving even.
