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.

TPS61299EVM-103 is an evaluation module for the TPS61299 boost converter with 95-nA quiescent current. TPS61299 is ideal for low quiescent products powered an alkaline or coin battery. Output voltage and fast transient mode can be selected by changing the jumper cap position.
Overcoming Low-IQ Challenges in Low-Power Applications
Designers of ultra-low-power electronics today make constant trade-offs between higher performance and longer battery life. Despite improved battery capacities, the fundamental challenge remains: how can higher performance be achieved for longer periods of time?
Time-Saving and Cost-Effective Innovations for EMI Reduction in Power Supplies
As electronic systems become increasingly dense and interconnected, reducing the effects of electromagnetic interference (EMI) becomes an increasingly critical system design consideration.
Understanding the Trade-offs and Technologies to Increase Power Density
A key to design success is often to reduce the size of the power supply. Space is limited. There is constant pressure to do more with less. More broadly, the miniaturization of power supplies has and will continue to enable new markets and applications.
LDO Noise Demystified
This application report explains the difference between noise and PSRR of an LDO. It also explains the different ways noise is specified in LDO datasheets and which specification should be used in the application. Finally, it explains how LDO noise is reduced.
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.

TPS62903-Q1
The TPS62903-Q1 is a highly efficient, small, and flexible synchronous step-down DC/DC converter that is easy to use. A selectable switching frequency of 2.5 or 1.0MHz allows the use of small inductors and provides fast transient response. The device supports high VOUT accuracy of ± 1.5% across the entire operating temperature range and enhanced load transient performance with the DCS-Control topology. The wide 3-V to 18-V input voltage range supports a variety of nominal inputs, like 12-V supply rails, single-cell or multi-cell Li-Ion, and 5-V or 3.3-V rails.
TPS929160-Q1
With the increasing demand for animation in automotive lighting, LEDs must be controlled independently. Therefore, LED drivers with digital interfaces are essential to effectively drive pixel controlled lighting applications. In exterior lighting, multiple lamp functions are typically located on different PCB boards with off-board wires connected to each other. It is difficult for a traditional single ended interface to meet the strict EMC requirements. By using an industrial-standard CAN physical layer, the UART-based FlexWire interface of the TPS929160-Q1 easily accomplishes long distance offboard communication without impacting EMC.

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.
How to enhance power and signal integrity with low-noise and low-ripple design techniques
Improving accuracy and precision and minimising system noise is a common challenge for engineers designing a power supply for noise-sensitive systems for medical applications, test and measurement, and wireless infrastructure that use clocks, data converters or amplifiers.
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.
