Description

The QPI-10 integrates a total hot-swap function with

an EMI filter for V•I Chip applications. The product

aligns with the AdvancedTCA

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.
