QuietPower® Output Ripple Attenuator Modules

Active output ripple attenuator

The QuietPower QPO output ripple attenuator products use proprietary active filtering to reduce power supply output ripple and noise (PARD) over 30dB from 1kHz. QPOs improve transient response, ensure 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.
