The
SP7619 Evaluation Board
is designed to help the user evaluate the performance of the SP7619 for
use as a single LED Driver. The evaluation board is a completely assembled and tested surface mount
board which provides easy probe access points to all SP7619 inputs and outputs so that the user can
quickly connect and measure electrical characteristics and waveforms. The Evaluation Board schematic
diagram is shown at Figure 1.
DESCRIPTION AND BOARD SCHEMATIC
Figure 1.The SP7619 Evaluation Board Schematic Diagram
*Note: While high current time duration is limited by the SP7619 in the range from 2 to 7s, we don鈥檛
recommend pushing the button for a long time to prevent LED damage and battery discharge. LEDs
provide very bright light at 0.5/0.7A output current. Protect your eyes.
