11.4 Performance Data

11.4.1 Line and Load Regulation

The existing limits for the EP-16 (LNK501) design are shown for reference. Key

differences to note are the higher no-load voltage, lower voltage at the peak power point

and the increase in the output current as the voltage falls in the CC region.

The lower voltage at the peak power point has the additional effect of increasing the

current at the power point. This could be adjusted by increasing the feedback resistor R1,

which would also increase the no-load voltage and no-load input power.
