Description
The QPO-1 output ripple attenuator SiP uses active filtering to reduce power supply output ripple and noise (PARD) over 30 dB from 1 kHz to 500 kHz. The QPO-1 operates over a voltage range from 3 to 30 Vdc and supports load currents as high as 10 A. Output regulation is maintained using remote sensing or the trim input of the power supply. The QPO-1 architecture improves transient response and ensures quiet point-of-load regulation. The QPO-1 reduces the required number of output capacitors to support dynamic loads.
Features
>30 dB PARD attenuation, 1 kHz to 500 kHz.
>20 dB PARD attenuation, 50 Hz to 500 Hz.
10 A rating over a 3-30 Vdc operating range.
Efficiency: Up to 99% with power limit protection.
User selectable optimization of attenuation, dissapation & transient load response.
1.0 X 1.0 X 0.2" SiP with SMT or LGA mounting.
Improves transient response of most DC-DC converters and power supplies.
Reduces required number of output capacitors to support dynamic loads.
Supports precise point-of load regulation.
Peak detector function adjusts for ripple amplitude variation.
Surface Mount LGA Package.
