The module can also be used in different power circuits, such as AC/DC and DC/DC, allowing it to cover a wide range of LED lighting needs.

Features

The STEVAL-ILL077V1 is equipped with several features that make it ideal for a variety of applications. The main features of the module include:• Wide input range of 4.5V - 60V.• Constant Current output.• Dimming range of 0.02 to 100%, adjustable via external dimming signal.• Operating temperature range from -40 to 125 ºC.• Small size, ideal for integration into small spaces.• High reliability and long lifetime.• Short-circuit protection and over-temperature shutdown.

Working Principle

The STEVAL-ILL077V1 is a constant current LED driver, which means that it ensures the output current stays constant regardless of changes in the input voltage. This is done by detecting the voltage drop across a current sensing resistor, converting it to a corresponding current, and adjusting the LED current accordingly. The LED current can also be adjusted to dim or increase the brightness of the LED over a whole range of 0.02 to 100% using an external dimming controller or PWM signal.The STEVAL-ILL077V1 module has an adjustable switching frequency, which can be set in the range of 300 kHz - 500 kHz according to the application requirements. The adjustable switching frequency helps to reduce EMI and achieve optimal efficiency for the application.The module also features a thermal shutdown circuit which will shut down the module in the event of an over-temperature event, protecting the module from further damage and ensuring the safety of all components and connected systems.

Conclusion

The STEVAL-ILL077V1 is a unique module, specially designed to meet the application needs of a wide range of LED lighting applications. Its features and special features ensure maximum performance and system reliability, making it a good option for many LED lighting applications. Its wide input voltage range and dimming range make it suitable for a variety of applications, while its adjustable switching frequency and thermally activated shutdown features provide the utmost protection for the system.
