Picor has released the QPI-8, the industry's first system-in-a-package device designed to integrate the total hot-swap function with an active EMI filter.

Vicor subsidiary Picor has released the QPI-8, the industry's first system-in-a-package (SiP) device designed to integrate the total hot-swap function with an active EMI filter.

As a complete solution, this integrated device greatly reduces product complexity and enables live insertion of plug-in cards and simultaneous EMI noise suppression for DC/DC convertor applications.

The QPI-8 complies with AdvancedTCA PICMG3.0 requirements for hot insertion and board-level conducted noise limitations to meet EN55022 class B levels.

At only 5mm high, this low-profile product simplifies the design challenge while occupying just 1in2 of valuable PCB space.

The EMI filter section provides active conducted common-mode and differential-mode noise attenuation from 150kHz to 30MHz.

The QPI-8 is designed for use on a 48 or 60V DC bus (36-76V DC).

The inrush current limit and circuit breaker functions are designed to support PICMG3.0 hold-up capacity requirements and 200W per board limit up to 70C PCB temperature.

The input under- and overvoltage features include hysteresis and are nominally set to 34 and 76V, respectively, and can be individually trimmed using external series resistors.

The power good output provides an optocoupler drive that can be configured to enable downstream DC/DC convertors with either active low or active high enable inputs.

The QPI-8 is available in a 25.4 x 25.4 x 5mm SiP with LGA mounting, packaged in antistatic tubes.

QPI-8-EVAL1 kits are available with a mounted QPI-8 with screw terminals for easy insertion and testing.
