 QPO-1LZ
QuitePower TM — Output Ripple Attenuation Sip
|
|
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. |
