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.
