The QPI-8 is the industry’s first System-in-Package (SiP) designed to integrate a total Hot-Swap function with an active EMI filter. The product aligns with the AdvancedTCA™ PICMG^® 3.0‚ requirements for hot insertion and board level conducted noise limitations. The EMI filter provides active conducted common-mode (CM) and differential-mode (DM) noise attenuation from 150 kHz to 30 MHz. The QPI-8 is designed for use on a 48 or 60 Vdc bus (36 – 76 Vdc). The inrush current limit and circuit breaker are designed to satisfy the 200 W per board PICMG^® 3.0 limit up to 70°C PCB temperature around the QPI-8. The undervoltage and overvoltage thresholds can be trimmed separately via the UVEN and OV inputs using external series resistors. The Power Good active-high output provides optocoupler drive for a converter’s active-low enable or active-high by connecting the diode in series with the Power Good output. The QPI-8 is available in a 1.0" x 1.0" x 0.2" SiP (System-in-Package) with LGA mounting. QPI-EVAL1 kits are available with a mounted QPI-8 and screw terminals for easy insertion and testing.
