The ISL6745UEVAL2Z is a high-performance, high-density, evaluation board specifically designed for LED driver applications. The board contains two independent, isolated separately regulated DC/DC converters for powering isolated LED strings. The board also contains an adjustable output current source, a single-ended primary control, and a high-side N-channel MOSFET, as well as a large variety of protection features.

The ISL6745UEVAL2Z board supports current-mode control for buck, boost or buck-boost operation, depending on the configuration. The current-mode control can be used to provide better light output modulation using pulse-width modulation (PWM) signals. The board also features an adjustable output current source, allowing the user to conveniently adjust the maximum LED string current. The output current can be adjusted easily using the external potentiometer, allowing the user to fine-tune settings for improved light output.

The board also provides an adjustable over-temperature protection (OTP) circuit, which can be configured to protect the LED driver from potential damage due to ambient temperatures that exceed the board’s threshold. The OTP circuit helps ensure the LED driver can work safely and efficiently in a wide range of environmental conditions. Furthermore, the ISL6745UEVAL2Z offers a wide range of safety features such as over-voltage protection (OVP), under-voltage protection (UVP), over-temperature protection (OTP) and hysteresis regulation.

The ISL6745UEVAL2Z also offers various test points allowing the user to monitor and measure the output current, output voltage, input voltage, and temperature. These test points allow easier debugging and testing of the board with any external meters or oscilloscope. Additionally, the board can also be used to evaluate the power performance of various LED drivers by testing the performance at different conditions such as load current and temperature.

In summary, the ISL6745UEVAL2Z evaluation board is a high-performance, high-density, evaluation board specifically designed for LED driver applications. The board contains two independent, isolated separately regulated DC/DC converters for powering isolated LED strings. It offers various protection features such as over-voltage protection (OVP), under-voltage protection (UVP), over-temperature protection (OTP) and hysteresis regulation. The board also offers test points to measure the output current, output voltage, input voltage and temperature. It can be used to evaluate the power performance of various LED drivers by testing the performance at different conditions such as load current and temperature.
