AdvancedTCA^TM Hot-Swap SiP With Active EMI Filter
Description
The QPI-8 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
AdvancedTCA^TM 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 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-8.
The undervoltage and overvoltage thresholds 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-8 is available in a 1.0" x 1.0" x 0.2" SiP (System-in-
a-Package) with LGA mounting. QPI-EVAL1 kits are
available with a mounted QPI-8 and screw terminals for
easy insertion and testing. For more information on
