100W Dimmable DC-DC LED Driver with Daylight Harvesting and Wireless Connectivity Reference Design

TIDA-01095

Design files

Overview

This reference design is a tested DC/DC LED driver for high power and 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 ZigBee. High bay and low bay LED lighting luminaires are replacing the fluorescent and HID lights as they reduce energy consumption in half and nearly eliminate maintenance costs. Daylight harvesting using the dimming feature combined with ambient light sensor can provide up to an additional 50% energy savings depending on the application. TIDA-01095 provides high efficiency DC/DC conversion, allows dimming, daylight harvesting and enables wireless connected lighting control.

Features
  • 100-W synchronous buck LED driver with an average of 97.3% efficiency over 100% to 50% brightness with analog dimming
  • 1:500 contrast ratio with analog dimming and 1:5000 with PWM dimming
  • Ambient light sensor OPT3001 based light measurement enabling daylight harvesting and constant lumen implementations in software
  • Overcurrent and over-temperature protection for driver and LED module
  • CC2650 platform enables connected lighting with Bluetooth Smart or ZigBee

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
