摘要

Until now, ringing choke converters, or RCCs, have been one of the least expensive ways to implement a switched-mode power supply in the sub-four-Watt power range. The high parts count, design-and-manufacturing difficul-ties, and inability to meet energy-efficiency standards inherent in RCC designs, however, make them poor can-didates to replace inefficient linear supplies. By understanding the shortcomings of the basic RCC design — and the need to reduce its part count, engineers can better understand how to design an efficient and economical switching supply for applications that require less than 4W. In many cases, power-conversion ICs that include all necessary control and monitoring capabilities offer an easy way to lower component count while enabling a power supply to meet new external power supply (EPS) energy-efficiency standards.
