The Vicor QPI-10LZ is an integrated hot-swap controller and EMI filter designed for AdvancedTCA (ATCA) PICMG 3.0 compliant boards. It offers robust protection and noise reduction for DC power inputs, operating on 36-76 Vdc buses, with a maximum input voltage of 80 Vdc and a 100 Vdc surge capability.
Key electrical features include a 6A breaker with delay and a 12A limiter, ensuring protection against overcurrent conditions. The integrated EMI filter provides significant common-mode (CM) and differential-mode (DM) noise attenuation, with over 40 dB CM attenuation and over 60 dB DM attenuation at 1 MHz. Efficiency is approximately 99%.
This device comes in a low-profile 25 mm x 25 mm x 4.5 mm LGA package, saving valuable PCB space. It operates within a PCB temperature range of -40°C to +100°C. The QPI-10LZ is designed to connect between OR'ing diodes and power conversion input hold-up capacitance, aligning with requirements for hot insertion and board-level conducted noise limitations.
The normal operating range is 36-76 Vdc, with a continuous maximum of 80 Vdc and a transient maximum of 100 Vdc for 100 ms.
It is housed in a 25 mm x 25 mm x 4.5 mm LGA (Land Grid Array) package.
