Overview

This webinar will be broadcast at 10 am EST, 7 am PST, 4 pm CET.

The inverting buck topology is a low noise method to achieve a negative output voltage. Through its buck output stage, a continuous output current is realized which results in a lower output voltage ripple. Additionally, a low-pass filter on the internal reference voltage attenuates 1/f noise. Combined together, these low-noise features eliminate the need for a post-DC/DC linear regulator (LDO) and cleanly power sensitive analog circuitry, such as data converters. This technical webinar explains both low-noise circuits and demonstrates their usefulness in sensitive analog signal chain applications.
