 QPO-2LZ
QUITEPOWER TM — Low Voltage Output Ripple Attenuator
|
|
The QPO-2 output ripple attenuator SiP uses active filtering to reduce supply output ripple and noise (PARD) by over 30dB from 1kHz to 500kHz. The QPO-2 is biased through the VAUX input and filters an input voltage range of 0.3VDC to 5.5VDC while supporting load currents as high as 20A. The VAUX input range is 7V to 12V with a minimum require difference between VAUX and QPOOUT of 7V. Output regulation is maintained by using either the remote sense or the trim adjustment of the power supply. The product can be used in an open loop configuration when ripple and noise reduction are the main objective and load regulation. |
Product Features
- >30 dB PARD attenuation, 1 kHz to 500 kHz.
- >20 dB PARD attenuation, 50 Hz to 500 Hz (1).
- 20 A rating over a 0.3-5.5 Vdc operating range.
- Up to 90-95% efficiency with load vs. headroom trim.
- User selectable performance optimization of the attenuation, power dissipation & transient load response.
- 25 X 25 X 4.5 mm SiP with LGA mounting.
- Closed loop control 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 optimizes headroom for ripple amplitude variation automatically.
- Patents Pending
