Vicor Intros New QPO-1 QuietPower Attenuator

Vicor Corp. (Andover, MA) announced its new QuietPower™ QPO-1 output ripple attenuation module, which uses active filtering in a SIP package to provide >20dB of conducted differential noise attenuation from 60Hz to 500kHz. The QuietPower module is rated for 10A and can be used with most switch-mode power supplies having output voltages from 3Vdc to 30Vdc.

The QPO-1 is the first product from Vicor’s new power IC subsidiary, Picor Corp., and it offers the basic functionality of Vicor’s µRAM quarter-brick module in a package one-tenth the size at one-third the price. The QPO-1’s closed-loop architecture improves the load transient response of the source power supply and features precise point-of-load voltage regulation. The SIP can control the source either through the remote-sense leads or through the voltage trim lead. The QPO-1 supports parallel operation for high-current requirements.

The SIP measures 1in x 1in x 0.2in (25mm x 25mm x 5mm). Units are surface-mountable with either land-grid-array or ball-grid-array terminations. The QuietPower QPO-1 modules are priced at $12 in OEM quantities and are available from stock.
