Lower noise for a negative output voltage rail

Date:
March 26, 2019

Duration:
05:46
You can have BOTH low noise and high efficiency on a negative voltage with just a DC/DC and no LDO.
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.
