Application Information
LEDs are typically wired in series to make a string of LEDs and then the strings can be wired in parallel to generate enough light. If only two or
three strings are wired in parallel then it is recommended to add resistors (e.g. 0.5R) to each string to help balance out the LED currents in each
string. All strings must share a common heatsink for better current matching.

A typical 1W high brightness white LED has a forward voltage of around 3.3V at its operating temperature and draws 350mA. Thus each LED
actually draws about 1.15W. Similarly, 3W white LEDs have usually the same forward voltage but can be run at 700mA or more. Using the LED
datasheet specification, the optimum LED arrangement and the best driver for each application can be worked out.
The tables below show some examples
. Other LED combinations may have different forward voltages at their recommended operating currents.
