DESCRIPTION AND BOARD SCHEMATIC

The

SP6652LED Evaluation Board

is a compact circuit that was built on SP6652 and can

provide a stable drive current for a 1W or 3W Luxeon type light source. The SP6652 is an

integrated synchronous buck regulator configured to provide constant output current for this

application. The evaluation board is a completely assembled and tested surface mount board

which provides easy probe access points to all SP6652 inputs and outputs so that the user can

quickly connect and measure electrical characteristics and waveforms.
