3 Operating the Evaluation Board
3.1 Setup
The LM2651_EVAL evaluation board comes ready to be tested. The only setup needed is connecting the
input voltage to the V
IN
and GND posts. The load and output are connected to the V
OUT
post.
3.2 Operating Conditions
The input voltage to the LM2651 regulator must be within the range of 4V to 14V DC for proper operation.
The device will not function properly with voltages below 4V and damage may occur if any voltage greater
than 16V is applied. Refer to LM2651 1.5A High Efficiency Synchronous Switching Regulator (SNVS032)
for all performance characteristics.
