The MAX17149ETE+T is a extremely versatile, efficient and robust compound LED driver solution. With the combined benefits of low external component count, enhanced security features and dynamic versatility, MAX17149ETE+T offers a superior alternative to single-function products for applications with multiple control, display and illumination requirements.

The MAX17149ETE+T is an integrated compound-LED driver and DC/DC buck converter solution, which is difficult and costly to achieve with discrete components. The integrated compound LED driver is especially important for applications that require a single-slope controller, such as managing current in automotive headlights with a smooth and consistent profile.

The pair of integrated buck converters and buck-boost converter provides multiple output voltages, ranging from 5V to 35V. The integrated boost converter allows the system to generate a very low load step and to provide high current LED lighting with a wide dimming range. The combination of the buck converters and buck-boost converter ensures that the complete power supply will drive up to 8 strings of LEDs with a single chip solution.

The MAX17149ETE+T is a PMIC (Power Management IC) designed for ease of use and for flexibility. It has built-in, secure protection features that provide reverse voltage protection and excess voltage devices. The integrated secure, low-cost ESD protection circuit allows for improved robustness in automotive, industrial and home appliance applications. The MAX17149ETE+T has programmable advanced configurable soft-start and system reset, as well as low-profile externally adjustable I2C-addressable temperature monitoring and supply current protection circuits.

The MAX17149ETE+T PMIC - LED Drivers can be used for a broad array of application fields, including general lighting and automotive headlights, for automotive display, rear combination lights, and for safety. For general lighting and automotive headlight applications, the MAX17149ETE+T can reference a single LED current source, or set LED current levels dynamically, to manage the LED module brightness from multiple sources. In an automotive display, the MAX17149ETE+T can provide regulated, constant current for several LED strings along with the protection circuits for the constant current sources, helping to improve and maintain the performance.

The MAX17149ETE+T is a versatile solution to many applications because of its integrated buck converters, boost converter, and ESD protection that allow it to safely and efficiently power up to 8 strings of LEDs and maintain safety parameters, while providing robustness in extreme operating conditions. As far as LED driver solutions go, the MAX17149ETE+T is an excellent solution for automotive headlights and automotive displays, general lighting, and safety applications.
