The LT3799EMSE-1#PBF is a high performance power management integrated circuit or PMIC, specifically a LED driver for automotive lighting systems. It is designed to offer superior performance with improved efficiency, reduced component count and superior thermal robustness. The PMIC is designed to allow automotive lighting developers to easily and effectively control intensities of LED lighting, with a simple and effective design. The device is suitable for use in applications such as LED fog lights, LED daytime running lights, LED tail lights and LED spotlights.

The LT3799EMSE-1#PBF is a three-channel LED driver; with each channel capable of nominal 500mA. Each channel can be individually dimmed via PWM with an effective resolution of up to 12-bits. The PMIC allows the designer to adjust the pulse width modulation frequency over a wide range, with a soft-start capability to simplify turn-on timing and dimming. The PMIC also offers an adjustable current limit, over-voltage protection and built-in protection against over-temperature and short-circuit conditions.

The main function of the LT3799EMSE-1#PBF is to provide a low voltage, wide input voltage range power supply for the LED lighting system. It features a wide operating range, from 10V to 65V. The PMIC’s on board synchronous rectifier reduces power losses and increases power efficiency. The LT3799EMSE-1#PBF also allows for independent dimming control of each channel, with a resolution of up to 12-bits and pulse width modulation frequency adjustable over a wide range.

The LT3799EMSE-1#PBF is designed to simplify the installation process of the LED lighting system. The device’s on-board components reduce the number of external components, while improving the overall system performance. The PMIC is designed to limit the current through the LED lighting system, while also suppressing interference between different channels by providing individual channel current limit and dimming. The device’s on-board over-voltage, over-temperature, and short-circuit protection provide additional safety and reliability.

The LT3799EMSE-1#PBF LED driver is designed to meet the rigorous standards of automotive lighting systems. The device is designed to provide superior performance, with all the essential analog control, protection and synchronization components integrated within a single, small 3mmx3mm package. The LT3799EMSE-1#PBF PMIC provides the necessary control, protection and monitoring features for automotive lighting applications in a single package, vastly reducing the number of components required for the LED lighting system.
