The solar-LED streetlight controller consists of one 80 W battery charger and one 25 W LED driver. During the daytime, when there is sufficient sunlight, the charger converts the electricity from the solar panel and charges the battery. At nighttime, the battery powers on the LED lamp as streetlight.

Demonstration circuit DC2342A is a 60V synchronous boost LED controller featuring the LT3762. It drives a single string of LEDs at 2A up to 32V when VIN is between 7V and 28V. It runs down to 4VIN with reduced ILED and can withstand VIN transients as high as 30V.

The MCP1643 Synchronous Boost LED Constant Current Regulator Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1643 device. This board demonstrates the MCP1643 in a boost converter application supplied by one AA battery, or from an external voltage source, which drives an LED with four selectable currents. The MCP1643 Synchronous Boost LED Constant Current Regulator E…

The LM3463 is a 6-channel linear LED driver with Dynamic Headroom Control (DHC) designed to drive six strings of high brightness LEDs at maximum supply voltage up to 95V. Each output channel of the LM3463 evaluation board is designed to deliver 200 mA of LED driving current. The LED turn-on voltage is set to 48 V by default, thus the board is able to deliver up to 57.6 W total output power.
