What is a low power design?

Low power design is a system using a collection of techniques and methodologies for the purpose of optimizing battery life and reducing the overall power dissipation of the system.

What is a low power system?

Consider a low-power system designed to run from two alkaline AA batteries. These batteries have a linear dis-charge curve and will discharge from 3.6V to 2.7V over the first 50% of the battery life. Using a low dropout 2.5V regulator, only about half of the battery capacity will be used before the regulator is below the minimum operating voltage.

What are low power components?

Choosing components designed for low power can have a significant impact on the overall power consumption of a device. Examples of Low-Power Components Low-Power DDR Memory (LPDDR): Consumes less power compared to regular DDR memory. Low-Power Microcontrollers: Designed to operate at lower voltages and frequencies.

What does low power mean?

Low power means different things for different systems. Some applications focus on dynamic power consumption as they must remain running constantly, such as a power supply. For these applications, the only concern is how to reduce dynamic power as much as possible to improve efficiency.

How to classify battery models?

Classification of battery models One of the first steps of battery modeling is to decide, what is the purpose of the modeling. Every application of the model requires slightly different approaches and parameters. There is no strict rule, how to categorize battery models, same models can belong to more than one class.

Does a low power system need a power supply?

The selection and design of a power supply for a low-power system can have major impacts on the power consumption of the system. Linear regulators, switching regulators and other PMICs all require some amount of power to operate, and many are tuned for systems with high-power requirements.
