Beschreibung

This document aims to assist engineers in designing different power applications and to provide an insight on how a simple, Non-Synchronous Boost Converter can be used to develop solutions for non-typical requirements.The following paragraphs will provide examples of converter applications that fulfill a wide variety of the industry requirements.The solutions provided by Microchip Technology Inc. highlight the use of the MCP1661/3 boost (step-up) regulators, which provide the necessary flexibility required in dealing with the increasing range of the technological field demands.The MCP1661/3 devices are compact, highly efficient, fixed-frequency, Non-Synchronous Step-up DC-DC Converters, which integrate a 36V switch. These products provide space efficient, high-voltage step-up, easy-to-use power supply solutions. The MCP1661/3 devices were developed for applications that are powered by two-cell or three-cell alkaline, Ni-Cd, Ni-MH batteries, or Li-Ion or Li-Polymer batteries.
