QPI-9LZ
Hot-Swap SiP with VI Chip EMI Filter for4 24 V VI Chip

|
 |
The QPI–9 includes the total hot–swap
function along with an EMI filter for VI 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 VI Chips. The QPI9 is
designed for use on a 24 Vdc bus. The inrush 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 VI Chip converter. |
