Description

The Picor QuietPower QPO output ripple attenuator products use proprietary active filtering to reduce power supply output ripple and noise (PARD) over
30 dB from 1 kHz. QPOs improve transient response, ensures quiet point-of-load regulation and works with most DC-DC converters and switching power supplies. Output regulation is maintained using remote sensing or the trim input of the power supply.
