Low Voltage Output Ripple Attenuator

The QPO-2 output ripple Attenuator SiP uses active filtering to reduce supply output ripple and noise (PARD) by over 30 dB from 1 kHz to 500 kHz. The QPO-2 is biased through the VAUX input and Filters an input voltage range of 0.3 Vdc to 5.5 Vdc while supporting load currents as high as 20 A. The VAUX input range is 7 V to 12 V with a minimum required difference between VAUX and QPO OUT of 7 V. Output regulation is maintained by using either the remote sense or the trim adjustment of the power supply. The product CAN be used in an open loop configuration when ripple and noise reduction are the main objective and load regulation is not as critical. The QPO-2 architecture improves transient response and ensures quiet point-of-load regulation when used with most switching power supplies. The performance waveform in figure 2 is an example of the ripple reduction and transient load improvement the QPO-2 CAN provide using a 3.3V brick style converter. By Vicor Corp.
