TLC5940 One Wire Control--Eliminating Microprocessor Control for Integr LED Driv

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
