Evaluation Boards – LED Drivers: IS31LT3135-V1GRLs2-EB

Light-emitting diode (LED) drivers are components that take on the specific tasks of powering LED devices. The IS31LT3135-V1GRLs2-EB is a controlled circuit from Pattern Group Inc. It is the updated version EB board for their LED driver, the IS31LT3135-V1GRLs2. The board helps to evaluate the LED driver’s performance and assists with development of more complex designs.

Application Field

The IS31LT3135-V1GRLs2-EB is designed to drive one or two white LED strings in a dimmable circuit. It is connected to an AC power source and has a very low annual energy consumption rate, making it an ideal choice for applications such as LED strip lighting, ambient lighting, and light bulb replacements. The board is also compatible with smart and manual dimming, allowing it to be used in applications in which LED brightness needs to be adjusted by a switch.The IS31LT3135-V1GRLs2-EB is a versatile component that is capable of performing a wide range of duties and meeting multiple design requirements. It is a great choice for designers and engineers working on projects such as portable lighting, automotive lighting, and energy-efficient lighting solutions.

Working Principle

The IS31LT3135-V1GRLs2-EB board is made up of a component cluster of an IC, resistors, and capacitors, as well as a PC interface which helps in programming the IC. The IC is programmed with a dimming on/off control signal and can be set to a variety of levels.When power is first supplied to the board, the IC and external components are ready to receive the dimmer control signal, designed to manually or automatically adjust the LED brightness. The control signal is sent to the IC, which is then used to adjust the current flowing through the LED strings. The LED brightness is then adjusted accordingly.The IS31LT3135-V1GRLs2-EB is also capable of detecting an open LED and a short LED on the LED strings. LED brightness will be reduced or turned off when an open LED or short LED is detected, protecting the LED strings from other failures. Additionally, the IS31LT3135-V1GRLs2-EB has the capability to simultaneously monitor both LED strings, and it will shut down the output power if one of the LED strings has an overload failure.

Conclusion

The IS31LT3135-V1GRLs2-EB is an advanced circuit board and solution that helps designers and engineers evaluate the performance of their LED drivers. The control signals on the board can be used to control the brightness of the LEDs, acting in applications such as portable lighting, ambient lighting and energy-efficient lighting solutions. Additionally, the board has the capabilities to detect an open or a short LED, as well as monitor both LED strings for overload failure and shut down the output power. The IS31LT3135-V1GRLs2-EB is an ideal choice for engineers and designers looking for a robust and reliable solution for their LED-based designs.
