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.

TO GET STARTED:

1. Connect VIN from VIN to GND (VIN range 2.7V to 4.2V).

2. Select mode between TORCH and FLASH by putting jumper into corresponding position.

3. Apply High to ON terminal to turn the LED on.
