This section describes the jumpers and connectors on the EVM and how to properly connect, set up, and use the LMR51430EVM.
VIN – Terminal TP1 Power input terminal for the converter. Adjacent to it is the GND reference
ground. Use this terminal to attach the EVM to a cable harness.
EMI IN+ – Terminal TP13 Input terminal for input filter of the converter. If an input filter is desired
between the supply voltage and the LMR38020, connect the supply voltage between
EMI IN+ and EMI GND (Terminal TP14) on the bottom layer.
VOUT – Terminal TP6Regulated output voltage for the converter. Adjacent to it is the GND reference ground.
GND – Terminal TP2, TP5, TP7, TP14Ground reference for the converter. Use these terminals to attach the EVM to a cable harness.
ENABLE SETTING – Jumper J1Used to enable the switch-mode converter. The device will be enabled when the EN pin is high, and disabled when low.
