Single DC/DC controllers with digital power control simplify system design in multiload applications

摘要

Designs in a variety of wall-powered systems have become increasingly challenging. New, strict efficiency standards have shaped the market, resulting in the reinvention of power architectures. Furthermore, system complexity has increased due to more demanding processing power, increased feature-sets and the addition of other supportive functions. Addressing such challenges, while keeping development time and system cost in mind, has become very difficult. Prioritizing and trading-off parameters and functions associated with power conversion and power management is also becoming a major headache.rnThis article discusses system design challenges in wall-powered equipment and introduces design solutions that can accomplish low-cost, intelligent power control, design flexibility and fast time-to-market. A single-output DC/DC controller with digital interface control will be introduced for addressing these challenges.
