Power supply opens door to reduce total SWaP of VPX systems

The XPm2220 provides up to 300 W of total combined output power at up to 90% efficiency, and it can be paired with another XPm2220 for load sharing and redundancy. A single XPm2220 can support up to 25 A on 12 V, 2 A on -12 V, 40 A on 5 V, 20 A on 3.3 V, and 4 A on 3.3 V Auxiliary. The XPm2220 also provides over 500 V of galvanic isolation between its input and output voltages and can be connected directly to a 28 VDC MIL-STD-704 or MIL-STD-1275 input without additional clamping or suppression.

Internal MIL-STD-461 EMI filtering enables the XPm2220 to eliminate the potential need for additional system-level power filtering within a deployed chassis. This can have a significant impact on reducing system SWaP, cost, and time to market. The XPm2220 also includes an Intelligent Platform Management Interface (IPMI) controller for monitoring input and output voltage, as well as board temperature, through the VITA 46 system management I2C interface.
