Guide to Choosing the Best DCDC Converter for Your Application
DC-to-DC switching converters are widely used in most portable devices. They efficiently generate various regulated supply voltages for different sub-blocks within the same system board. A typical system board for any portable device can easily contain many switching converters. This huge market leads to the existence of hundreds of different DC-DC converters provided by multiple suppliers. These converters range from tiny packaged parts with no external components to large parts with multiple external components for proper operation, making it difficult to choose the best option.
This white paper introduces a procedure for choosing the proper DC-DC switching converter for a given application. It explains basic, performance, and optional metrics in detail. It also demonstrates other practical aspects that are sometimes overlooked by system designers. Multiple application examples are provided.
