Hot-swap SIP with active EMI filter

10 August 2005 Power Electronics / Power Management

Vicor subsidiary, Picor's QPI-8, is 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 converter applications, according to the company.

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 5 mm high, this low-profile product occupies just 6,5 cm² of valuable PCB space. It has LGA mounting.

The EMI filter section provides active conducted common-mode and differential-mode noise attenuation from 150 kHz to 30 MHz. The QPI-8 is designed for use on a 48 or 60 V d.c. bus (36-76 V d.c.). The in-rush current limit and circuit breaker functions are designed to support PICMG3.0 hold-up capacity requirements and 200 W per board limit up to 70°C PCB temperature.
