Light Temp click is a dual-channel LED driver, designed to be used in tunable Smart Connected Lighting (SCL) applications. It is based on the AL1782, a dual-channel PWM dimmable linear LED driver. By utilizing a high-frequency E-flicker free technology with Deep Dimming capability, it can be used in both single-channel dimmable white and dual-channel tunable white SCL applications. The AL1782 IC features the Adaptive Thermal Management scheme, reducing power dissipation. It also integrates an abundance of protection features for increased reliability: undervoltage, open or short circuit at the output, and thermal protection.
The AL1782 integrates two low-side current sinks which allow LED strips or LED bulbs to be connected in the common-anode topology for increased effectiveness and power optimization. This IC is designed with the power optimization in mind: whenever there is no valid PWM signal on its input pins, it enters the low-power mode, preventing unnecessary power dissipation. An additional ADC IC is used, allowing advanced power optimization.
Light Temp click offers good reliability, linear dimming response, and low power consumption. It is a perfect solution for smart lighting applications, SCL LED bulbs, but also for driving LED strips and high-power LEDs.
