The LM3450A evaluation board is designed to provide an AC to LED solution for a 30 W LED load. Specifically, it takes an AC mains input and converts it to a constant current output of 700 mA for a series string of 1 to 13 LEDs (maximum LED stack voltage of 45 V). There are two assembly versions designed to operate from two different nominal AC input voltages, 120 VAC or 230 VAC.
* For Constant Current, the board must be modified as described on page 8 of the user guide. * Streetlight applications require that the power supply designed to power an LED lamp must have high efficiency and at least an equivalent lifetime in order to guarantee maintenance-free operation during the life of the LED.
* For Constant Current, the board must be modified as described on page 6 of the user guide. * This application note describes the characteristics and features of a 130 W demonstration board (EVL130W-SL-EU), tailored on an LED power supply specification for street lighting.
This engineering report describes a non-isolated 14 W output and high-line input voltage range (195 VAC–265 VAC) power supply utilizing the TNY279GN for an LED lighting application.
The STEVAL–LLL003V1 evaluation board is a constant current LED driver, based on non-isolated buck topology using VIPer0P. The board delivers 130 mA ± 2.5% at an output load of 15 – 21 white LEDs.
The STEVAL-LLL006V1 board is designed to help you evaluate high power LED lighting solutions with comprehensive power management and wireless connectivity. The board integrates an intelligent power conversion stage thanks to the HVLED001A LED lighting controller with various operating modes, sensing and protection mechanisms, and highly efficient switching based on the STP21N90K5 Power MOSFET.
The STEVAL-ILL053V2 evaluation board implements a 130 W LED power supply for street lighting. The circuit is composed of two stages: a front-end PFC using the L6562AT, and an LLC resonant converter based on the L6599AT.
RDK-801 is a 100 W LED ballast with 3-way dimming function. The LED ballast is designed to provide a 48 V output voltage across 0 mA to 2080 mA output current load with 3-way dimmable constant current at 48 V – 36 V LED voltage string. The design is optimized to operate from an input voltage range of 100 VAC to 277 VAC.
The EVL012LED is an LED driver board. This architecture is based on a two-stage approach: a front-end PFC preregulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that embeds the controllers of both sections in the same device
