DESCRIPTION AND BOARD SCHEMATIC

The

SP6137LED Evaluation Board

is designed to help the user evaluate the performance of

the SP6137 for use as a Luxeon 1W/3W/5W Driver. The evaluation board is a completely

assembled and tested surface mount board which provides easy probe access points to all

SP6137 inputs and outputs so that the user can quickly connect and measure electrical

characteristics and waveforms.
