STEVAL-ILL054V1

The STEVAL-ILL054V1 Evaluation Board – LED Drivers is a versatile solution in the field of LED lighting applications. It is designed as an evaluation board with two main functions. First, the board acts as a driver to allow the LEDs to be powered over a wide voltage range. Second, it functions as an inte-regulated power supply that ensures that the LEDs are current limited and stepless dimmable over the AC voltage range.

The STEVAL-ILL054V1 evaluation board is based on the STHV091AP high-voltage OFF-line SMPS step-down controller. This controller incorporates all the features needed for driving high-power LEDs over a wide AC input voltage range, including input over-voltage protection, current-mode control, soft-start and a fixed 180kHz frequency. The STEVAL-ILL054V1 is a tiny board designed to demonstrate the performance of the STHV091AP.

The board provides a complete LED driver platform for the STHV091AP to drive high-power LEDs. The STEVAL-ILL054V1 can drive up to a maximum of 700mA. The high power LED connections are configured in series with the common ano-de connecting to one of the LEDs and the other LED connecting to the pin marked as “LEDC”.

One of the key features is the wide AC input voltage range. The STEVAL-ILL054V1 is marked with a range of 85V to 280V AC. This enables it to be used in applications such as lighting up to 6W, 8W and 10W retrofit bulbs. The board also supports a wide dimming range allowing dimming of LEDs between 50% (approx. 5mA) and 100% (approx. 700mA).

The STEVAL-ILL054V1 has an additional feature which is the universal input voltage range of 85V to 265V which allows it to be used with almost any AC source. The universal input voltage feature makes it suitable for the retrofit or indoor lighting bulbs or other applications that require a universal voltage input.

The STEVAL-ILL054V1 evaluation board is designed to provide a high-quality LED driving solution. It has been designed to be safe, reliable and energy efficient. The controller allows the LED to be powered over a wide range with great colour consistency. It is also designed with special circuitry to protect the circuit from overvoltage and short-circuit conditions. This ensures that the LED will be protected against voltage transients and overloads ensuring safe and stable operation.

The STEVAL-ILL054V1 evaluation board is an excellent solution for LED lighting applications. It is a great solution for retrofit, landscape and other LED lighting applications that require a wide AC input voltage range. The board provides a complete LED driver platform for the STHV091AP to drive high-power LEDs with a wide dimming range and colour consistency. The universal input voltage feature adds to the flexibility of the board making it suitable for almost any AC source. Lastly, the board also provides protection against voltage transients and overloads ensuring safe and stable operation.
