9.2 Regulation
9.2.1 Output Voltage and Line
The line regulation result shown above is typical for a design where the phase angle
dimming mode of U1 is selected (to provide a very wide dimming range). For a given line
voltage the output current can be centered by changing the value of the FEEDBACK
resistor (R15). The table below shows the resistor values to adjust the mean output
current at specific input voltages,
