TLC5928PWPR, a member of the Texas Instruments\' TLC5928 12-bit constant-current LED sink driver family, provides constant-current control with excellent supply voltage rejection and fast switching time. Specifically designed for driving white and RGB LEDs with up to 4 channels, the TLC5928PWPR is designed with a low-cost SOIC 8- pad package. This driver has excellent features such as a wide supply voltage range of 2.7V to 5.5V, fast switching time of 18ns, variable brightness control, extended temperature range of -40℃ to +85℃ and integrated overcurrent protection.
Application Field and Working PrincipleThe TLC5928PWPR is a high-efficiency, constant-current source driver, ideal for various applications including display, automotive, and general illumination. In automotive applications such as daytime running lamps (DRLs), rear fog lamps and parking lamps, the TLC5928PWPR can be used to achieve excellent dimming control, providing efficient and cost-effective lighting solutions. In display and general illumination applications, the TLC5928PWPR can achieve high-efficiency and consistent color by driving dense white and RGB LED arrays. The TLC5928PWPR can also provide excellent supply voltage rejection and fast switching times, providing a versatile and cost-efficient LED driver solution.
The working principle of the TLC5928PWPR LED driver is based on a simple buck-boost control scheme. The LED driver will draw constant-current from supply and sink it to the LED with a series of passes. The TLC5928PWPR uses a high-efficiency PWM modulation scheme to regulate the LEDs\' brightness. This PWM modulation scheme is capable of high-efficiency and accurate dimming.
The TLC5928PWPR also offers high-resolution and adjustable pulse width modulation to control the brightness of the LEDs. The pulse width is adjustable so that the brightness of individual LEDs can be adjusted as per the requirement. The TLC5928PWPR also provides a range of adjustable features such as output current and frequency, and time period.
The TLC5928PWPR has low-cost, high-performance, and low-power consumption characteristics, providing a cost-effective solution for display and general illumination applications. The driver also features short-circuit protection and built-in overcurrent protection to ensure optimal operation when driving LED arrays. The TLC5928PWPR is tolerant to a wide input supply range, allowing LED arrays to be driven from a larger battery or from a regulated voltage source.
In summary, the TLC5928PWPR is a high-efficiency 12-bit LED driver, an ideal solution for various applications including automotive, display and general illumination. It offers adjustable current and adjustable pulse width modulation for accurate control of LED brightness and provides excellent supply voltage rejection and fast switching times. The low-cost SOIC 8-pad package and the integrated overcurrent protection make the TLC5928PWPR the perfect LED driver for cost-effective LED solutions.
