Extending battery life with a boost converter

A device’s quiescent current, or IQ, is an important parameter for low-power, energy-efficient end equipment such as continuous blood glucose monitors (CGMs). The current drawn by the integrated circuit at light or no loads significantly influences power losses in standby mode and the total run time of the system.

How can power ICs reduce inherent and system noise?

Low-noise low-dropout linear regulators (LDOs) and switching converters, precision monitoring, and reliable protection are fundamental to enabling precision signal chains. For applications such as the battery monitoring of medical, test and measurement, battery monitoring of electric vehicles, and more TI uses dedicated power process technologies and advanced circuit and test techniques that increase accuracy, minimize distortion, and reduce noise across both linear and switching power converters.

Powering Sensitive ADC Designs with the TPS62913 Low-Ripple and Low-Noise Buck Converter

High speed analog to digital converters are notoriously sensitive to power supply noise. The most common solution to minimise that noise is to use linear power supplies, or a switch mode power supply (SMPS) from the main bus rail followed by a low dropout regulator. Compared to a linear supply, there are two big advantages of being able to use a SMPS alone: the reduction in power loss and the size of the power supply. To use a SMPS alone requires careful consideration of the switching supply selected, as well as the design and layout of the SMPS to achieve the desired results of the same performance with lower power dissipation and smaller board space.

Designing an application to support a wide input voltage and battery voltage

It can be challenging for engineers to design applications using rechargeable batteries that provide the best charging experience for consumers when different projects have different battery-charging needs. Using a different battery charger for every application increases design time because you have to redesign, debug, and requalify every new circuit.
