3 Operating the Evaluation Board
3.1 Setup
The LM2651_3.3V_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 LM2651-3.3 regulator must be within the range of 4 V to 14 V DC for proper
operation. The device will not function properly with voltages below 4 V and damage may occur if any
voltage greater than 16 V is applied.
