QPO-1 Output Ripple Attenuation SIP
Description:
The QPO-1 output ripple attenuator SiP uses active filtering to
reduce output the periodic and random disturbances (PARD)
over 30 dB from 500 Hz to 500 kHz and it can be extended
down to 50 Hz with additional capacitance added to the VREF
pin
(1). 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 with remote sense or trim
adjustment of the power supply. The closed loop architecture
improves transient response and ensures quiet point-of-load
regulation when used in conjunction with the power supply’s
control loop or trim node.
The waveforms in Figure 2 show the
QPO-1’s ability to both filter a
converter’s
output
ripple
and
maintain a constant output voltage
during a load transient. The input
voltage of the QPO-1 (dark blue)
shows
varying
amplitude
and
frequency PARD before and during
the load transient, but the QPO-1
output voltage (light blue) remains relatively unaffected. The
converter used is a Vicor Mini, 48 Vdc to 5 Vdc converter
(Model number: V48B5C200BN).

10A load step (~1A/s).
Typical Application
Figure 3 - Typical Application: SC/Trim supports applications that don’t
require remote sense.
Note 1: For off-line supplies, 20 dB of attenuation can be achieved down to 50 Hz with additional capacitance (CHR) added from the VREF pin to the REFGND pin.
