Note:
1)
Due to board’s small size,
thermal dissipation is limited and may exceed the over-
temperature shutdown threshold.
2)
The MxC 292 can be powered from 24V delivering 6V to the buck regulator. The
minimum VIN for the TPS565201 is 4.5V.
3)
Other buck regulator output voltages are available by changing R4. Refer to the VOUT
Table in Figures 13 and 14.
