4.3 Power Connections
Multiple power connection options are available on the Lite5200B evaluation system.
4.3.1 DC Power Jack
–
J35
The J35 DC power jack provides a 5V, fused, input which is capable of supplying the Lite5200B system.
5V is regulated into 4 separate power domains. Care should be taken to ensure that the supplied voltage
does not exceed 5V.
4.3.2 ATX Power Connector
–
J36
The J36 molex connector provides an interface to any standard commercial of the shelf power ATX
supply.
Note: The connector on the board has pin 1 labeled as pin 4.
Please notice that pin 1 on the board has the square pad and
is nearest SW4. Ignore the pin label on the connector itself.
