TM
Hot-Swap SiP with V•I Chip EMI Filter
Description
The QPI-10 integrates a total hot-swap function with
an EMI filter for V•I Chip applications. The product
TM
aligns with the AdvancedTCA PICMG3.0‚
require-ments for hot insertion and board level
conducted noise limitations. The EMI filter provides
conducted common-mode (CM) and differential-mode
(DM) noise attenuation from 150 kHz to 30 MHz.
The QPI-10 is designed for use on a 48 or 60 Vdc bus
(36 – 76 Vdc). The inrush current limit and circuit
breaker are designed to satisfy the 200 W per board
PICMG3.0‚ limit up to 70°C PCB temperature around
the QPI-10.
The under and overvoltage thresholds can be trimmed
separately via the UVEN and OV inputs using external
series resistors. The QPI-10 provides two Power Good
signals, with one referenced to the input ground and
the other to the output ground, which can be used to
enable other circuits along with the V•I Chip converter.
