DESCRIPTION AND BOARD SCHEMATIC
The
SP7685EB Evaluation Board
is a compact circuit including the SP7685 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
SP7685 inputs and outputs so that the user can quickly connect and measure electrical
characteristics and waveforms.
SP7685EB Schematic
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.
