Introduction
This document is provided as a supplement to the datasheet for the IRMCK203. It provides detailed information about the internal design and external interfaces of the product and describes how to configure the operation to conform to the requirements of a custom application. This document is intended for engineers who are developing an application using the IRMCK203 digital control IC.

The document is divided into three main sections. In the Concepts section, system design concepts are presented and theory of operation is described in detail. This section provides the background needed to begin IRMCK203 application development. The Techniques section provides practical “how-to” information, tips and examples to assist with the development process. The Reference section provides a complete definition of the host register map with a short description of each register and field. The registers are listed in sequential order for easy reference.
