The design helps control LED lights using less power. It supports dimming, works with light sensors, and saves energy in indoor or outdoor spaces.
Texas Instruments’ TIDA-01095 is a DC-DC LED driver reference design made for high-power, dimmable lighting applications. It uses a wireless system-on-chip (SoC) platform that enables light control through analog dimming, PWM, or Bluetooth Low Energy (BLE). The design also supports daylight harvesting by pairing with ambient light sensors, offering additional energy savings—up to 50%—by automatically adjusting light output based on natural light availability.
This reference design is aimed at industrial and commercial lighting setups, including indoor high-bay and low-bay fixtures commonly used in warehouses, factories, and large facilities. It can also be used in outdoor environments, such as area lights and street lights, and supports distributed DC lighting systems where power is managed centrally and delivered across multiple fixtures.
The system uses efficient DC-DC power conversion and allows for both manual and automatic dimming control. It supports energy savings not just through the switch to LED lighting but also through the integration of sensors and connected control systems. When natural daylight increases in a space, the lighting system can reduce artificial light output, cutting power use without affecting illumination levels.
At the heart of the design are the TPS92640 and TPS92641 high-voltage synchronous NFET controllers, used in buck-current regulator configurations. These controllers regulate output current using valley current-mode control with a controlled on-time architecture. This method keeps the switching frequency nearly constant and simplifies loop compensation, improving system stability.
The devices include a high-voltage start-up regulator that supports a wide input voltage range from 7 V to 85 V. The integrated PWM controller supports high-speed switching, up to 1 MHz. Deadtime between the high-side and low-side gate drivers is optimized for high efficiency across a broad range of input voltages and load conditions.
Both controllers support analog and PWM dimming inputs, allowing flexible dimming control. A low-offset error amplifier and proprietary PWM dimming logic ensure linear response and allow the LED current to drop to true zero when needed. A precision reference output is also included to power a low-power microcontroller if needed.
Protection features include cycle-by-cycle current limiting, overvoltage protection, and thermal shutdown. The TPS92641 additionally supports shunt FET dimming and includes a built-in MOSFET driver for high-resolution PWM dimming.
Overall, the design combines energy-efficient LED lighting with flexible, sensor-based control and robust power conversion. It supports long operational life, stable light output, and smooth dimming, making it a strong fit for industrial, commercial, and smart lighting systems.
