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.

*Note: While high current time duration is limited by the SP7619 in the range from 2 to 7s, we don’t

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.
