2.1.1 Input and Output Connector Description

  • VIN — Terminal TP2 – Power input terminal for the converter. Adjacent to this terminal is the GND reference ground. Use this terminal to attach the EVM to a cable harness.
  • VOUT — Terminal TP4– Regulated output voltage for the converter. Adjacent to this terminal is the GND reference ground.
  • GND — Terminal TP3, TP5 – Ground reference for the converter. Use these terminals to attach the EVM to a cable harness.
  • Enable Setting — Jumper JP1 – Used to configure the enable circuit. Leave the pins open or short Pin2 with pin3 enables the circuit, short Pin2 to Pin1 disables the circuit. See Table 2-1 for details.
Table 2-1 EN Connections
EN Connection Configuration
Leave all pins of JP1 openEnable, EN connect to VIN through a pullup resistor
Short Pin2 with pin3, leave Pin1 openEnable, Programmable system UVLO by EN divider
Short Pin2 with pin1Disable, EN connect to GND directly
  • Test point — TP6, TP7, TP8, TP9, TP10, TP11 are test points. See Table 2-2 for details.
