Application Requirements Drive Choice of Voltage Regulator in Portable Systems
Today's smartphones and other portable devices offer an ever expanding plethora of functions. Coupled with the rising demands of multi-voltage designs, the next generation of new products poses a significant challenge as portable system designers struggle to manage power consumption and extend battery life. Fortunately, a variety of voltage conversion technologies are available to help designers tackle this task. By better understanding the tradeoffs that each voltage conversion approach offers and matching them with the unique requirements of each function block in a handset design, portable system designers can maximize power efficiency and, in the process, enhance the probability of their product's success in the marketplace.
