Evaluation Boards - LED Drivers

The CAT4104AGEVB evaluation board is an LED driver developed for use in a variety of applications. The board is powered by a 5V supply and provides up to 8 channels of constant current output for LED lighting or backlighting applications. The CAT4104AGEVB is equipped with IC controller and LED selection switch options on each channel, allowing users to select different LED types such as CREE, Infineon, Osram, or other compatible LED brands. Additionally, the board has an advanced level-shifting voltage translator that provides up to 20V of bias voltage to power more complex LED lighting designs.

The CAT4104AGEVB has a versatile design that allows it to be used in a variety of applications. It can be used as a standalone LED lighting solution, and is suitable for dimmable LED lighting applications. It also has a wide temperature range operating temperature range of -40°C to 85°C, making it ideal for extreme environments. Additionally, the board is designed with a low stand-by current to save power and extend battery life.

Working Principle of CAT4104AGEVB

The CAT4104AGEVB is a pulse width modulation (PWM) controller, which uses current and voltage waveforms to control the LED current of each output channel. The waveforms are generated based on the input pulse edge times, or duty cycles, and transmitted through the MOSFETs to the respective LEDs to adjust the illumination intensity. The CAT4104AGEVB also implements PWM dimming protection to protect the LEDs from high current transitions.

The CAT4104AGEVB features an internal voltage regulator that ensures proper operation when connected to a DC supply. The output current of each channel can be adjusted with a potentiometer on the board, while the maximum output current is selected by a jumper. The board also implements over-temperature protection, over-current protection, and short-circuit protection. Additionally, the board has input and output pins that allow users to interface the board with their system (e.g. software, LCD displays).

Applications of CAT4104AGEVB

The CAT4104AGEVB is an ideal solution for a wide range of lighting applications, including automotive, general lighting, and consumer electronic applications. It can be used for backlighting applications, such as LCD and LED displays, and also for LED lamps, spot lights, and billboards. Additionally, the board can be used in highbay and industrial lighting applications, such as downlights, floodlights, and street lighting.

The CAT4104AGEVB can also be used in solar applications, such as solar powered street lights or solar powered LED signs. Furthermore, the board can be used in other applications, such as LED lighting for amusement parks or large areas, or for emergency signage or emergency vehicle lighting.
