The MAX17129EVKIT+ evaluation board is an LED driver board developed by Maxim Integrated, a global manufacturer of analog, linear and power devices. Utilizing the high power and performance MAX17129 LED driver integrated circuit, the evaluation board can easily drive LED strings of up to 40 V and 40 mA each with a robust protection design. This versatile board is suitable for a variety of LED driver applications in a wide range of applications such as automotive headlamps, backlighting and industrial lighting.

The MAX17129EVKIT+ is a current-mode buck-boost LED driver that can source and sink up to 40 mA of LED current. The evaluation board features both analog- and pulse-width modulation (PWM) dimming options, allowing for dynamic control of brightness from 0 to 100%. An integrated protection circuit provides overtemp, LED open/short, inductor short and reverse polarity protection, making it an ideal LED driver solution for applications that require high reliability and long lifetimes.

The evaluation board includes an input voltage range of 4.5-18V. The upper limit of the input voltage may differ depending on the output voltage, efficiency and other conditions. The MAX17129 requires a minimum input voltage of 4.5V and can support up to a 40V output voltage. A variable output voltage allows the user to adjust the desired output voltage, making it suitable for driving LEDs in various applications. The board can be set to continuous current mode to maintain a constant current load on the LEDs, or to a more efficient pulsed mode for improved efficiency and higher output power.

For maximum performance, the MAX17129EVKIT+ includes a two-phase regulated bucket-boost switching controller, which ensures a stable output voltage even when the output current is varying. The switching frequency of the controller is user adjustable with a range of 200 kHz to 400 kHz. The device provides overvoltage protection of 40V and under-voltage protection of 4.5V, enabling the board to efficiently drive LED arrays of varying voltages without needing to change any of the internal components.

The MAX17129EVKIT+ evaluation board also includes adjustable soft-start and current-limit protection. With the current limiting feature, the board can be configured so that the current is limited to a safe maximum level, offering improved protection to the LEDs and other components.

The MAX17129EVKIT+ is the perfect evaluation solution for evaluating MAX17129 LED drivers and creating a custom LED driver solution. The on-board electronic components and easy-to-use setup help to reduce development time and improve system performance. Thanks to its high power efficiency and stable performance, the MAX17129EVKIT+ is suitable for a wide range of LED driver applications, such as automotive headlights, backlighting and industrial lighting.
