Hot-Swap SiP With V I Chip EMI Filter  
Description  
Features  
• >50 dB CM attenuation at 1 MHz  
• >70 dB DM attenuation at 1 MHz  
• 40 Vdc (max input)  
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  
• 100 Vdc surge 100 msec  
• 707 V hipot hold off to shield  
• 6 A breaker with delay plus 12 A limiter  
• 25 x 25 x 4.5 mm SiP (System in Package)  
• Low profile LGA package  
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  
• -40° to +100°C PCB temperature (See Fig. 5)  
• Hot-swap & filter combined saves PCB space  
• Efficiency >98%  
• Connects between OR’ing diodes & power  
conversion input hold-up capacitance  
• Patents pending  
other circuits along with the V I Chip converter.  
Applications  
• Industrial and Military COTS
