End of Life QPI-8 QUIETPOWER AdvancedTCA Hot-Swap with Active EMI Filter Description: Features: The QPI-8 incorporates a total hot swap function with an EMI 40 dB CM attenuation at 250 KHz (50) filter for DC/DC converter applications. The product aligns 70 dB DM attenuation at 250 KHz (50) with the AdvancedTCA PICMG3.0 requirements for hot 80 Vdc (max input) insertion and board level conducted noise limitations. The 100 Vdc surge 100 ms EMI filter provides active conducted common-mode (CM) and 1,500 Vdc hipot hold off to shield plane differential-mode (DM) noise attenuation from 150 kHz to 30 6 A delayed circuit breaker rating, 12 A current limited MHz. The QPI-8 is designed for use on a 48 or 60 volt DC bus 25.3 x 25.3 x 5.2 mm Lidded SiP (System-in-Package) (36-76VDC). The in-rush current limit (12A) and circuit 24.9 x 24.9 x 4.4 mm Open-frame SiP breaker (6A) are designed to satisfy the 200W per board Low profile LGA package PICMG3.0 limit up to 70 C (T ) before de-rating. A -40 to +125C Ambient temperature (see Figure 19) Efficiency >99% The under and over voltage thresholds can be trimmed Connect in series for higher attenuation separately via the UVEN and OV inputs using external series TV Certified resistors. The Power Good active low output can be used to disable a converter until its input bulk capacitors are fully charged to the bus voltage. The QPI-8s active filter greatly reduces the amount of board space typically required for EMI Applications filtering. ATCA blades The QPI-8 is available as a lidded Telecom base stations or an open-frame SiP (System-in- IBA & distributed power Package) with LGA mounting. Network switches and routers Evaluation boards are available to Optical line-cards allow for quick in-circuit testing of TD-SCMA wireless infrastructure the QPI-8LZ within an existing system design.
