应用须知

  • TLC5940 One Wire Control--Eliminating Microprocessor Control for Integr LED Driv
    PDF, 410 Kb, 档案已发布: 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

  • LED Display System Module Using Cascading TLC5940 Devices
    PDF, 496 Kb, 档案已发布: Jul 6, 2006
    Described in this document are application ideas and reference designs for the TLC5940 LED driver. The following application example shows the building of a basic module of an LED display system using a cascading connection on n TLC5940 devices connected to a controller. The reference design implements three TLC5940 devices to drive 16 LEDs.
  • Using the TLC5940 with Higher LED Supply Voltages and Series LEDs
    PDF, 353 Kb, 档案已发布: Aug 20, 2007
    This application report describes how to accommodate higher LED supply voltages and increase the number of series LEDs that the TLC5940 can drive.
  • Grayscale and Dot-Corrected LED Display Using TLC5941 (Rev. A)
    PDF, 198 Kb, 修订版: A, 档案已发布: 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, 档案已发布: 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
  • Hardware Design Considerations for a Wireless LED based Display Design
    PDF, 682 Kb, 档案已发布: Jun 11, 2014
    Scoreboards have different purposes with various features. Scoreboards are typically used for displaying scores of a game played between two teams. These games can be a timed or an untimed event. The application described in this application report creates a multi-sport scoreboard that is cost efficient, portable, and easy to use. The display values on the scoreboard are transmitted wirelessly.
