Hot-Swap SiP With V^•I Chip EMI Filter
Description
The QPI-9 includes the total hot-swap function along
with an EMI filter for V•I Chip applications. The EMI
filter is designed to attenuate the conducted
common-mode (CM) and differential-mode (DM) noise
generated by the higher switching frequencies of the
V•I Chips. The QPI-9 is designed for use on a
24 Vdc bus. The in-rush current limit and circuit
breaker are designed to deliver over 140 W of power
with an input voltage of 24 V on the converter.
The QPI-9's internal fault timer allows it to operate
safely in the event of a short across its output. The
QPI-9 enters a retry mode where it will attempt to
restart until the short condition is removed. The under
and over voltage thresholds can be trimmed separately
via the UVEN and OV inputs using external series
resistors. The QPI-9 provides two Power Good signals,
PWRGD1 referenced to the input ground and PWRGD2
to the output ground, which can be used to enable
other circuits along with the V•I Chip converter.
