XPm2220

The XPm2220 is a VITA 62-compliant 3U VPX power supply. The XPm2220 takes in a MIL-STD-704 or MIL-STD-1275 28 VDC input voltage and provides up to 300 W on 3.3 V, 5 V, and ±12 V at up to 90% efficiency. The XPm2220 also provides on-card MIL-STD-461E EMI filtering and MIL-STD-1275 transient suppression.

The XPm2220 fits in a VITA 62-compliant 3U VPX 0.8 in. or 1.0 in. slot. 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 can be supported on each rail, separately. The XPm2220 can provide a combined total output power of up to 300 W at maximum operating temperature. The XPm2220 also can optionally be paired with another XPm2220 for load sharing.

The XPm2220 features an Intelligent Platform Management Interface (IPMI) controller which monitors board input and output voltages and temperatures. In addition, the IPMI controller can turn off output power and monitor Nuclear Event Detection circuitry.
