Low noise DC/DC

A deep dive into the DC/DC + LDO approach

Understand the performance and trade-offs of the traditional low noise and high efficiency approach of using a DC/DC followed by an LDO, through a deep dive into TIDA-01566. The size, quiescent current, efficiency, temperature rise, noise, and adaptability of three different approaches are compared: DC/DC + LDO, DC/DC only, and LDO only.

Low noise DC/DC

Lower noise for a negative output voltage rail

What you will learn in this webinar:

  • How to achieve a low noise at a negative output voltage with the inverting buck topology
  • Understanding how the buck output stage and filtered reference voltage attenuate noise
  • The elimination of LDOs when powering data converters by utilizing these low-noise features

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.

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.
