External/Internal LED Drivers

The Texas Instruments TLC5946RHBR is a 16-channel, 12-bit, constant-current LED driver that is designed to provide high-quality, energy-efficient lighting solutions. It is a popular choice for a variety of applications, including LED strips, RGB lighting, and other LED-based lighting systems.

Description:

The TLC5946RHBR is a monolithic, 16-channel LED driver that uses a constant-current sink architecture to provide high-quality, flicker-free lighting. It is available in a 32-pin, 5mm x 5mm, very thin quad flat no-lead (VQFN) package. The device operates from a single 3.3V to 5.5V supply and can drive up to 16 individual LED channels with programmable current levels.

Features:

1. 16-channel, 12-bit LED driver with constant-current sink architecture
2. Wide operating voltage range (3.3V to 5.5V)
3. Programmable current levels for each channel
4. Independent brightness control for each channel
5. PWM control for each channel for flicker-free operation
6. Dot correction to ensure uniform brightness across all channels
7. Internal oscillator for precise timing and synchronization
8. Short-circuit and over-temperature protection
9. Small package size (5mm x 5mm VQFN)

Applications:

1. LED strip lighting
2. RGB lighting systems
3. Automotive interior and exterior lighting
4. Architectural and landscape lighting
5. Display backlighting
6. General-purpose LED lighting

The TLC5946RHBR is a versatile and powerful LED driver that can be used in a wide range of lighting applications. Its high-quality, energy-efficient performance makes it an excellent choice for designers looking to create visually appealing and energy-saving lighting solutions.
