Description and Introduction

LED Driver W/Shift Register, Data Latch, Constant Current Circuitry & Common Driver The TLC5920DL is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Channels:** 16  
- **Output Current:** 5–120 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3–5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Power Dissipation:** 1.5 W  
- **Package:** SSOP-24  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TLC5920DL is designed for driving LEDs with constant-current outputs, ensuring uniform brightness. It features a serial-in, parallel-out shift register with latched outputs and includes thermal shutdown protection.  

### **Features:**  
- **Constant-Current Outputs:** Independent current setting per channel via a single external resistor.  
- **High-Speed Data Transfer:** Supports clock frequencies up to 30 MHz.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Low Standby Current:** Reduces power consumption when inactive.  
- **Cascadable Design:** Multiple devices can be daisy-chained for expanded LED control.  
- **Open-Circuit Detection:** Helps identify faulty LED connections.  

This information is based solely on the manufacturer's datasheet.
