Buck Converters Proliferate in Handhelds as Features and Processing Power Increase
Portable consumer electronics are integrating many new features. System designers are challenged to meet the consumer’s expectations for small physical size and long battery life. Each new product feature requires extra space and extra processing horsepower. Meanwhile, there is less room left for the battery and an increasing demand for higher power-supply output current with greater efficiency in a smaller space. This application note recognizes these current demands on power-supply design and compares different regulator types for use in small portable devices.
