EVM Performance Characteristics
(1)
The default output voltage of this single-output EVM is 5 V. Efficiency and other performance metrics can change based on
operating input voltage, load current, externally-connected output capacitance, and other parameters.
(2)
The maximum output power delivered by the LM5180-Q1 PSR flyback converter increases with input voltage.
(3)
The selected flyback transformer provides functional isolation to 1500 V DC.
