SC451 - Single Phase Power Supply Controller

Download the SC451 datasheet PDF. This datasheet also covers the SC451ITSTRT variant, as both devices belong to the same single phase power supply controller family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
