The ISL59532IK-EVAL is an evaluation board designed for use with a high-voltage analog dimmable ballast for HID lamps – typically used in warehouses, factories, and street lights. It offers an inexpensive route to test and evaluate the performance of the ISL59532IK family of dimmable LED drivers.

The ISL59532IK is a high performance constant current, high-voltage LED driver that enables designers to take advantage of today\'s advanced LEDs. It features a wide input voltage range, adjustable peak current limiting, adjustable over temperature protection, and hot-plug robustness. It is designed to be integrated into a dimmable LED driver and compatible with legacy dimming systems such as non-digital and 0-10V analog dimming systems.

The ISL59532IK-EVAL evaluation board enables users to evaluate the capabilities of the driver and its associated components. It has two independent outputs that can be used to drive a single or dual channel LED driver with adjustable current level using a single digital control point. The onboard dimming network, temperature sensor, protection circuitry, voltage booster and phase-dimmable LED current sense amplifier provide an ideal platform for testing the performance of the driver in the application.

The evaluation board includes a powertrain stage that enables designers to reduce external component counts and optimize the driver for maximum system performance. The control and dimming interface is also provided, allowing designers to integrate the dimming signal from external systems. An integrated temperature sensing circuit is also included to protect the device from over-temperature conditions.

The ISL59532IK-EVAL has an output adjust range of 0.1-30V, and is compatible with a wide selection of LED drivers, including those from leading LED driver companies such as Cree, Bridgelux, and many others. A separate voltage regulator supplies an adjustable voltage to a wide range of LED strings, while the integrated PWM dimming signal interface provides compatibility with 0-10V dimming systems and the I2C interface enables compatibility with digital dimming systems. The evaluation board also includes LED current sense amplifier with adjustable current sense resistors to enable precise and accurate dimming control.

The ISL59532IK-EVAL also provides an integrated reference voltage and UVLO (Under Voltage Lock Out) circuitry, which enables designers to implement robust power management techniques. Additionally, an integrated temperature protection circuit provides protection against over temperature and sink gate turn off protection (SGOTO), which helps to protect the device from shorts and current surges.

Overall, the ISL59532IK-EVAL evaluation board is an ideal solution for customers who are looking to develop and evaluate LED lighting applications. A comprehensive suite of software and hardware solutions are also provided, allowing customers to quickly create the ideal solution for their specific needs. With the wide selection of software and hardware tools, users can easily create their own custom LED drivers, dimming systems, and other specialized LED lighting applications.
