SC457 Datasheet Single-phase Single Chip Vcore Power Supply

Manufacturer: SEMTECH

Overview: SC457 POWER MANAGEMENT.

General Description

The SC457 is a single phase, high performance PWM controller designed to power advanced processors.

On-chip support is provided for VID on-the-fly transitions and active voltage positioning.

The SC457 implements hysteretic control technology providing the fastest possible transient response while avoiding the stability issues inherent to classical PWM controllers.

Key Features

  • include programmable soft-start, open-drain PG_DEL and PG# outputs, dynamic current sharing, over-voltage and programmable over-current protection. The SC457 is available in a space-saving 32-pin MLP package. Single-Phase Single Chip Vcore Power Supply Features Single-Phase Solution with Integrated Drivers Hysteretic Control for Fast Transient Response Active Voltage Positioning True Differential Remote (die) Sensing On-Chip Support for all Power Management Features Programmable Soft-Start and.
