Picor Intros QuietPower QPO-1 Attenuator SiP

Picor Corp. (Andover, MA), a power IC subsidiary of Vicor Corp. (Andover, MA), introduced the QuietPower™ QPO-1 output ripple attenuator SiP, which uses active filtering to reduce power supply output ripple and noise over 20 dB from 1 kHz to 500 kHz. The QPO-1 is suitable for telecom base station and hand-held power, point-of-load power systems, low-noise power sensors, and medical instrumentation.

The QPO-1 operates over a voltage range from 3 Vdc 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 ensure quiet point-of-load regulation. The QPO-1 reduces the required number of output capacitors to support dynamic loads. The QPO-1 will work with most dc-dc converters and switching power supplies.
