Extending Battery Life with Low-Iq and Dynamic Voltage Scaling
PDF, 342 Kb, File published: Apr 1, 2020
When designing a battery powered system maximizing battery life is often one of the most important design goals. This is especially true in applications such as smart and IoT sensors or wireless medical equipment where some parts need to operate continuously at a low power level and the cost of replacing the battery is high. Selecting the right converter to obtain a fixed system voltage in such a
