LM3406MHEVAL: 350mA ~ 1.5A @ 18.9V (24V in), 6 ~ 42Vin

Summary

The LM3406 circuit and BOM that come pre-installed on the evaluation board are optimized to run from an input voltage of 24V, but the circuit can operate from a wide input voltage range of 6 ~ 42V.

The current output ranges from 0.35A to 1.5A. Figure 2 shows the program jumper settings used to program currents of 0.35A, 0.7A, 1A, and 1.5A.
