7 Power supply
The EVB requires an external power supply voltage of between to +12V/
≥2A. This allows the EVB to be easily used in a
vehicle if required. The 12v input is on the EVB is used to supply a FS26/SBC
– U1, the power management IC controller
pr5.0V, +3.3V and +1.5V, for the different power configurations of VDD_HV_A, VDD_HV_B, V15 and other
interfaces.

Connector Description
Ground
V+ (+12Volts).
2.1mm Barrel Connector
– J3
This connector should be used to connect the supplied wall-plug mains
adapter. Note
– if a replacement or alternative adapter is used, care must be
taken to ensure the 2.1mm plug uses the correct polarization as shown
Ground
V+ (12Volts).
2-Way Screw Type Connector
– J5
This can be used to connect a bare wire lead to the EVB, typically from a
laboratory power supply. The polarization of the connectors is clearly marked
on the EVB. Care must be taken to ensure correct connection.
