Universal Noise Attenuator Fits In SIP

Compatible with most switchmode dc supplies from 3 to 30 Vdc, the QPO-1 output ripple attenuation module provides active filtering in a 25 mm x 25 mm x 5 mm SIP. It provides greater than 20 dB of conducted differential noise attenuation from 60 Hz to 500 kHz and is rated for 10A. The module's closed-loop architecture is said to improve 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 its remote sense leads or through the voltage trim lead. It also supports parallel operation for high current requirements. Available in surface-mount, land-grid array, or BGA terminations, price is $12 each in OEM quantity. VICOR CORP., Andover, MA. (800) 735-6200.
