(cPCI) Backplanes

The XPm2000 changes the rules on what can be done with a 3U power supply. The XPm2000 takes in a MIL-STD-704 28V-DC input voltage and provides up to 200 W on 3.3V, 5V, and ±12V at up to 90% efficiency. The XPm2000 also provides on card MIL-STD-461E EMI filtering.

An innovative hold-up design drastically reduces the size of the hold-up capacitance and allows the capacitor to be retained on-card while maintaining up to 110 ms of hold-up time. The XPm2000 also supports the use of external hold-up capacitors for providing additional hold-up time.

The XPm2000 fits in a 3U cPCI or VPX 1.0-in pitch slot. Up to 8.3 A on 12V, 2 A on -12V, 20 A on 5V, and 25 A on 3.3V can be supported on each rail, separately. The XPm2000 can provide up to a combined 200 W of total output power at maximum operating temperature. The XPm2000 can also be paired up with another XPm2000 for load sharing.
