NXP Semiconductors MPC5748G User Manual

Initial Setup
4. Initial Setup
This section details the power, reset, clocks, and debug configuration which is the minimum
configuration needed in order to power ON the LCEVB.
4.1.
Power Supply Configuration
The Power supply
section is located in
the bottom left corner
of the LCEVB
The LCEVB requires an external power supply voltage of 5 V DC, minimum 1 A. There is a single 3.3
V switching regulator on the LCEVB providing MCU and peripheral power.
CAUTION
Connecting a power supply with a voltage greater than 5 V will
result in irrecoverable board damage. Check the power supply
voltage before connecting the plug to the LCEVB.
4.1.1.
Power Input Connector
Power is supplied to the LCEVB via a 2.1 mm connector from the wall-plug mains adapter as shown
below. Note – if a replacement or alternative adapter is used, care must be taken to ensure the 2.1 mm
plug uses the correct polarization as shown below:
Figure 3. 2.1 mm Power Connector
4.1.2.
Power Switch
Slide switch SW2 can be used to isolate the power supply input from the EVB voltage regulators
if required.
 Moving the slide switch to the right (away from the power connector) will turn the EVB ON. 

 Moving the slide switch to the left (towards the power connector) will turn the EVB OFF. 
