Power Interface Module (ATCA)
    Open-frame, single board construction for higher reliability
ATCA Power Interface Module The IQ65033QM10, IQ65033QGA12, and IQ665033QTA14 iQor™ Power Interface Modules integrate all features required by the AdvancedTCA Base Specification for a frame board power entry into a Quarter-Brick footprint. Minimal external components are required for all the key functions. Efficient utilization of hold-up capacitance with adjustable high-voltage management. Available in standard module or full-feature with I2C interface.
