Application Note 50: Implementing the RC5050 and RC5051 DC-DC Converters on Pentium® Pro Motherboards

This document describes how to implement a switching voltage regulator using an RC5050 or an RC5051 high speed controller, a power inductor, a Schottky diode, appropriate capacitors, and external power MOSFETs. This regulator forms a step down DC-DC converter that can deliver up to 14.5A of continuous load current at voltages ranging from 1.3V to 3.5V. A specific application circuit, design considerations, component selection, PCB layout guidelines, and performance evaluations are covered in detail.
