Evaluation Board for Active EMI Filters with Hot-Swap

The QPI-8 Evaluation board provides an easy to use

evaluation platform for testing the QPI-8 EMI filter with

Hot-Swap in existing or prototype systems. The board

comes with a mounted QPI-8, RPG (PWRGD=Power Good)

pull-up resistor, ROV and RUVEN jumper resistors, and

screwterminal blocks for electrical connections.

Please refer to the QPI-8 datasheet for detailed

description and typical operation of the product when

applying this evaluation board. Specifically refer to Figures

9a and 9b in the datasheet for detailed application

circuits.

Also refer to QPI-AN1 for critical PCB layout and EMI

considerations for QPI products in general but refer to the

individual product specifications for their PCB layout

footprint and pin-out.

External resistors can be used in series with the UVEN and

OV inputs to the BUS+ terminal to increase the threshold

voltages or connected directly for minimum specified

thresholds. Values can be determined using figure 6 of the

datasheet to trim these parameters up to the desired

levels. Optional C2 capacitor is described for hold-up

considerations during a power dropout and C3 can be

added to filter nuisance over voltage low energy spikes

that do not merit a shutdown condition.
