Analog and Interface Power Conversion Design Guide2Portable Power Conversion Design GuideDesign Guide Introduction and ContentsDC/DC Conversion Step-Down (Buck) Switch Mode Power ConvertersPortable Power Conversion applications present unique and challenging Design considerations. Innovative, small electronics require solutions with small footprints. In order to maintain battery life, Portable applications require both high Conversion efficiency and low standby Power dissipation. Multi-cell battery packs may require step-down (buck) conversions and single cell batteries often require step-up (boost) conversions to maintain consistent Power levels while the batteries discharge. Some products require constant voltage regulation for microcontrollers, sensors or RF signal processing; while some circuits need constant current regulation for backlighting or battery charging.

For wide input range voltage sources and high output current applications switch-mode power converters offer a significant increase in efficiency compared to linear regulators. This results in longer battery run time in portable applications.
