Evaluation Boards - LED Drivers

NCL30002LED2GEVB Application Field and Working Principle

The NCL30002LED2GERVB is an evaluation board from ON Semiconductors that has been designed to provide a comprehensive test platform for its NCL30002 LED Driver IC. The board is capable of driving up to 4 series LEDs on a single channel. Connecting to the Evaluation Board (EVB) allows the examination of the IC\'s basic performances and extra features, such as its dimming strategies, thermal characteristics, and its pulse-width modulation (PWM) behavior. The EVB is also capable for testing additional features such as chip-enable logic, drive duty cycle compensation, and more.

Application Field

The EVB can be used to test the NCL30002 LED driver IC in various applications including automotive lighting, camera flashes, microdisplays, and RGB light strips. The board can be used to measure performances such as OLED drive current accuracy, efficiency performance, light output power, brightness consistency, and additional features such as dimming control and thermal characteristics. The application flexibility of this EVB makes it applicable for various consumer electronic devices.

Working Principle

The EVB contains several components that are used to accurately measure the performance of the linked NCL30002 driver IC. The core of the EVB lies within its dedicated NCL30002 driver IC that allows the user to control the power supply and other driver settings, such as the PWM frequency, which can be adjusted with a stepped switch on the board. The EVB also contains a temperature sensor that can be configured with a high temperature shutdown in order to protect the linked NCL30002 driver IC.

The EVB also contains several other components that allow the user to examine the linked IC\'s additional features. These components offer the user the possibility to examine features such as logic enable inputs, dim caps, and biased low-side gate drive, as well as accurate calculations for peak current, shutdown voltage and more. Other features available for testing include those for a BOM list and propagation delay.
