Description

The TIDA-01095 TI design is a tested DC-DC LED driver subsystem for high power, high efficiency dimmable LED luminaires. It is built-on a wireless SoC platform which can enable intensity adjustment through analog, PWM dimming and control using any BLE smart device or ZiBee. High Bay and Low bay LED lighting luminaires are replacing the fluorescent and HID lights as they cut energy consumption in half and nearly eliminate maintenance costs. Daylight harvesting using the dimming feature combined with ambient light sensor, can provide up-to additional 50% energy savings depending on the application. TI design TIDA-01095 provides high efficiency DC-DC conversion, allows dimming, daylight harvesting and enables wireless connected lighting control.
