100W dimmable DC/DC LED driver reference design supporting daylighting and wireless connectivity

TI reference design TIDA-01095 has been tested as a DC/DC LED driver subsystem for high-power, high-efficiency dimmable LED luminaires. The design is built on a wireless SoC platform and enables brightness adjustment via analog as well as PWM dimming and control using any Bluetooth Smart device or ZiBee. High-bay and low-bay LED lighting fixtures are set to replace fluorescent and HID lamps as they cut energy consumption in half and virtually eliminate maintenance costs. Harvesting daylight by combining dimming with an ambient light sensor can result in additional energy savings of up to 50%, depending on the application. TI Reference Design TIDA-01095 provides high-efficiency DC/DC conversion that supports dimming, daylight harvesting, and wireless networked lighting control.

characteristic

• ● With analog dimming, 100W synchronous buck LED driver achieves 97.3% average efficiency over 100% to 50% brightness range
• ● Analog dimming can achieve a contrast ratio of 1:500; PWM dimming can achieve a contrast ratio of 1:5000
• ● Light measurement based on ambient light sensor OPT3001 supports daylight collection and constant implementation of lumens through software
• ● Provide over-current and over-temperature protection for drivers and LED modules
• ● The CC2650 platform supports networked lighting control through Bluetooth smart devices or ZigBee
