Note:
1)
Maximum thermal dissipation occurs when high currents are drawn from 6VOUT. Due
to board’s small size, thermal dissipation is limited
and may exceed the over-
temperature shutdown threshold.
2)
The 24VOUT output provides 0.5A and 12VOUT/6VOUT outputs provide 1A. Actual
delivered power depends on the output voltage of each stage.
3)
The MxC 290 can be powered from 24V delivering one-half the output voltage at pins 6-
8 as stated in Table 3.
