DESCRIPTION AND BOARD SCHEMATIC

The SP6685EB Evaluation Board is a compact circuit including the SP6685 in 3x3mm DFN and 3 small 0603 capacitors which can provide a stable drive current for a 1W LED such as the 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 SP6685 inputs and outputs so that the user can quickly connect and measure electrical characteristics and waveforms.
