RC5054 Datasheet

Programmable Synchronous DC-dc Converter Controller For Low Voltage Microprocessors

Manufacturer: Fairchild (now onsemi)

RC5054 Overview

The RC5054A provides plete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The RC5054A integrates all of the control, output adjustment, monitoring and protection functions into a single package.
