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.
