Due to the significant increase in semiconductor electronic applications and the development of its market, many types of PMICs (Power Management ICs) have been developed. Among them, LED drivers with the same application can be used to enhance the reliability and performance of LED lighting systems. MAX16814BUTP+ belongs to PMIC - LED Drivers. In this section, it will focus on the application field and the working principle of MAX16814BUTP+.

Application Field

MAX16814BUTP+ provides highly efficient power management for LED lighting systems and meets various LED application needs. This product line is a compact, single-channel, linear LED driver that achieves superior lighting quality, better system efficiency, and longer lifetime than conventional LED drivers. It can be used for a variety of applications, especially high/low/constant power LED lights as well as 24V/100V backlighting systems. MAX16814BUTP+ is typically used in applications like interior/exterior automotive lighting, spotlighting, linear lighting, wire-harness lighting, and control lighting.

Working Principle

The MAX16814BUTP+ is the second generation of the well-known MAX16814 linear LED driver. It works by continuously adjusting the forward drop of the LEDs to regulate their brightness efficiently. It increases the system performance in two simple steps: first, by reducing the forward drop of the LEDs and second, by increasing the boosting efficiency of the driver. In this way, the efficiency of the entire system can be significantly improved. MAX16814BUTP+ adjusts and maintains the forward drop of the LEDs in order to reduce the system’s power consumption and improve its energy efficiency.

MAX16814BUTP+ also provides superior protection against short circuit and over current conditions. It also offers adjustable current-limited protection to meet specific application requirements. MAX16814BUTP+ allows based dimming operations to be implemented easily, and its low output voltage of 80V allows for improved system compatibility and reduces component requirements for the application. It also supports input voltages ranging from 5V to 24V, allowing LED lights to be powered with either direct or poppin currents. Moreover, the LED driver features a pin-to-pin compatible, 4-wire serial digital interface (SDI) that allows maximum flexibility in color and brightness control, allowing it to be highly integrated into lighting control systems.

In summary, the MAX16814BUTP+ is an efficient, economical, and reliable single-channel linear LED driver for a variety of LED applications. It offers superb protection against short circuit and over current conditions, adjustable current-limited protection, and base dimming, making it highly compatible with lighting control systems. Additionally, its low output voltage of 80V and support for input voltages ranging from 5V to 24V make it ideal for high/low/constant power LED lights and 24V/100V backlighting systems.
