  • TLC5940 One Wire Control--Eliminating Microprocessor Control for Integr LED Driv
    PDF, 410 Kb, Datei veröffentlicht: Sep 25, 2006
    LED drivers such as the TLC5940 provide many integrated features that require a microprocessor interface to use. When these features are not needed, the TLC5940 can be configured with a single-wire interface for simple on/off control. This provides a low-cost solution to drive multiple LEDs with tight current matching while still allowing for PWM dimming in applications such as backlighting or gen

  • Grayscale and Dot-Corrected LED Display Using TLC5941 (Rev. A)
    PDF, 198 Kb, Revision: A, Datei veröffentlicht: Mar 5, 2008
    The TLC5941 LED driver uses a serial data interface to receive grayscale and dot correction data. This application report discusses the hardware and firmware to drive the TLC5941 with a MSP430F427 microcontroller.
  • LED Driver--Paralleled Outputs Provide High Current Outputs
    PDF, 957 Kb, Datei veröffentlicht: Sep 25, 2006
    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
