QPI-8L

The QPI-8L is the industry's first System-in-a-Package (SiP) designed to integrate a total Hot-Swap function with an active EMI filter. The product aligns with the AdvancedTCATM 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-8L is designed for use on a 48 or 60 Volt DC bus (36 76 Vdc). The in-rush 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-8L.

The undervoltage and overvoltage thresholds of QPI-8L can be trimmed separately via the UVEN and OV inputs using external series resistors. The Powergood active-high output provides opto-coupler drive for a converter's active-low enable (see Figure 9a) or active-high by connecting the diode in series with the Powergood output (see Figure 9b).

The QPI-8L is available in a 1.0" x 1.0" x 0.2" SiP (System-ina- Package) with LGA mounting. QPI-EVAL1 kits are available with a mounted QPI-8L and screw terminals for easy insertion and testing. For more information on Evaluation Boards visit us online at picorpower.com.
