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.
