The Texas Instruments LMR54410EVMevaluation module (EVM) helps designers evaluate the operation and performance of the LMR54410 wide-input buck regulator.

Figure 1-1 LMR54410EVM Board

EVM Features

• 4-V to 36-V input voltage range
• Default 3.3-V output
• Up to 1-A output current
• 1100-kHz switching frequency
• Hiccup mode short current protection
• Internal compensation

The EVM contains one DC/DC converter (see Table 1-1).

This section describes the jumpers and connectors on the EVM and how to properly connect, set up, and use the LMR54410EVM.

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.

VOUT — Terminal TP3 – Regulated output voltage for the converter. Adjacent to it is the GND reference ground.

GND — Terminal TP2, TP4 – Ground reference for the converter. Use these terminals to attach the EVM to a cable harness.

ENABLE SETTING — Jumper JP1 – Used to enable the switch-mode converter. The device will be enabled when the EN pin is high, and disabled when low.
