DESCRIPTION AND BOARD SCHEMATIC

The SP6686EB Evaluation Board is a compact circuit including the SP6686 in 3x3mm DFN and 3 small 0603 capacitors which can provide a stable drive current for a 1W LED such as the AOT White LED, Lumi-LEDs Luxeon I or PWF1 type light sources. The evaluation board is a completely assembled and tested surface mount board which provides easy probe access points to all SP6686 inputs and outputs so that the user can quickly connect and measure electrical characteristics and waveforms.
