LED Driver--Paralleled Outputs Provide High Current Outputs
This application report describes how to use the TLC5922, TLC5923, and TLC5924 to drive high-current LEDs. These ICs are designed to provide 16 individually controllable constant-current sinks. However, the 16 outputs can be connected in parallel to increase the current drive capability. Paralleling the outputs of these ICs allows the TLC5922, TLC5923, and TLC5924 to drive high-power LEDs such as the OSRAM Golden DRAGON™ and LUMILEDS Luxeon series of high-current LEDs.
