Low noise DC/DC

You CAN have both - low noise AND high efficiency

For noise-critical portable applications, such as GPS receivers, connectivity, and sensing, power supply designers always had to choose between longer battery run time (from higher efficiency) or higher signal chain performance (from the increased sensor sensitivity possible with a quieter power supply). For line-powered industrial or communications equipment applications, designers have been forced to dissipate significant amounts of power in LDOs to achieve the desired noise performance. Achieving both low noise and high efficiency was impossible.

Wide Input DC-DC Converters Servicing Low Quiescent Current Needs in Industrial Applications

Battery life cycle is a key for high-cell-count battery pack-based end-equipment. Low quiescent current (Iq) consumption of DC-DC converters is a major feature that helps achieve longer battery life cycles. TI’s latest buck converters boast low Iq consumption as they maintain high efficiency in the active mode (heavy loads) as well as extend battery life during standby modes. This training will cover an overview of battery powered industrial applications and the specific power consumption requirements for these end equipments.

Low noise DC/DC

Why place an LDO after a DC/DC?

Understand the performance and tradeoffs of the traditional low noise and high efficiency approach of using a DC/DC followed by an LDO.  Visualize other systems that could use the same approach, with the appropriate DC/DCs and LDOs in different packages and with different features.

What low quiescent current means for your application

You've heard of low quiescent current, or low Iq, but what does it mean for your design? In this training, learn how low quiescent current impacts your power supply performance, along with the benefits of alower quiescent current DC/DC switching converter
