MAX17061EVKIT+ LED driver evaluation board is designed to demonstrate and evaluate the performance of MAX17061 LED driver, a high voltage, high precision LED driver integrated circuit. Its design allows the user to develop multiple LED string configurations from a single 6.5V to 20V input voltage source. It features an easy to use system that can support up to 8 constant-current LED strings. The keys to the MAX17061EVKIT+ LED driver is the MAX17061 LED driver IC, an integrated inductor and kickback diode, and a variety of current-setting resistors. The EVKIT also includes a number of optional components to help users step up their design from the reference design level.

The application field of MAX17061EVKIT+ includes general purpose LED backlighting, automotive exterior lighting, general purpose lighting, RGB lighting, and other lighting or display applications. It gives the user flexibility in a wide range of configurations. From automotive applications such as exterior lighting to commercial and industrial applications, such as backlighting, the MAX17061EVKIT+ helps users to develop prototypes quickly and reliably.

The working principle of MAX17061EVKIT+ is based on the MAX17061 LED driver integrated circuit. The MAX17061 contains an array of logic and analog control circuitry and a high voltage source (VH) capable of driving multiple strings of high-current, high brightness LEDs. Using a combination of feedback, pulse-width modulation (PWM) dimming, and direct voltage mode dimming, the MAX17061 controls the current of the LEDs with low total harmonic distortion (THD).

The MAX17061EVKIT+ LED driver evaluation board includes three output current settings, each of which can be configured to operate in either constant voltage (CV) mode or constant current (CC) mode. In CV mode, the LED strings are driven with a fixed voltage and the LED string current is determined by the external LEDs\' forward voltage and internal LED string resistance. In CC mode, the MAX17061 sets the current to the LED string with a sense pin, which monitors the voltage across the shunt regulator\'s sense resistor.

The MAX17061EVKIT+ clearly achieves efficient, reliable LED string operation and is suitable for many LED lighting applications. It provides a platform for the design and evaluation of LED control systems. It demonstrates a highly reliable LED control solution, with robust constant current operation, low total harmonic distortion, and a variety of dimming options.
