8.4.2 Standby Mode

The LM5013 enter standby mode during light or no-load on the output. The LM5013 enters standby mode to prevent draining the input power supply. All internal controller circuits are turned off to reduce the current consumption. The quiescent current in standby mode is 25 μA (typical).
