North Atlantic 55MQ2 next-generation 3U, cPCI DC/DC converter
North Atlantic Industries (NAI) has available its next-generation 3U, cPCI DC/DC converter. The 55MQ2 provides 150 W (+5, +3.3 and ±12 VDC) at full load over its operating temperature range of -55 to +85°C (conduction cooled and measured at card edge).
This design is suitable for military airborne, shipboard and ground applications. The 55MQ2 is designed and manufactured to NAVSO P3641 component derating guidelines and each unit receives ESS screening.
The device contains an integrated EMI filter compliant with MIL-STD-461E. Its input is compliant with transient requirements of MIL-STD-704A to E. It is available with optional compliance for MIL-STD-1275, with reverse polarity protection.
It is fully compliant with PICMG 2.11, 47-position connector pin-out. It fits standard 3U cPCI or VPX 0.8″ pitch. It is a true single slot solution (does not interfere with inter-board separation plane on either side).
It is compatible with the power management bus and provides current share capability to implement increased power output or for load sharing of two or more units. It is available with an optional I2C communication bus.
Additional features include remote error sensing, short-circuit protection, current limiting and overvoltage protection. Typical efficiency is 80%.
