Buck转换器在手持产品中的应用

便携式消费类电子产品集成了越来越多的新功能。随着用户对更小尺寸、更长电池寿命的期盼,系统设计人员面临着更大的挑战。每种新增功能都需要额外的空间和额外的功率,这样,留给电池的空间将会更小,需要在更小的空间内以更高的效率提供更大供电电流。本文就电源设计中的电流要求对不同类型的调节器进行比较,阐述它们在便携产品中的应用效果。

The Application of Buck Converters in Handhelds

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 article recognizes these current demands on power-supply design and compares different regulator types for use in small portable devices.
