>30 dB PARD attenuation, 1 kHz to 500 kHz
Supports precise point-of-load regulation
Up to 99% efficient
High density, low profile LGA package
Reduces required number of output capacitors
to support dynamic loads
User selectable optimization of attenuation,
power dissipation, and transient load response
Compatible with most DC-DC converters
The QPO output ripple attenuator products use proprietary active
filtering to reduce power supply output ripple and noise (PARD) over
30 dB from 1 kHz to 500 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.
Load capacitance using this active technique can effectively be
reduced by a factor of 10, providing equivalent transient
performance. In the typical application schematic below the QPO
was inserted between the converter and the load using no additional
load capacitance. As shown in the performance plot, the drop in
load voltage (approx. 10 mV; channel 2) was significantly reduced
when compared to the converter output (approx. 100 mV; channel
1) with a 10 A transient load current step. The ripple voltage
amplitude was also reduced by a similar factor at the load.
