When considering power management integrated circuits (PMICs) for lighting applications, there is a broad range of products that can be used. Among these is the LM3642TLE-LT/NOPB, a member of Texas Instruments’ (TI) Power Management and Lighting Solutions family of integrated circuits. As a member of the Power Management and Lighting Solutions family, the LM3642TLE-LT/NOPB falls into the category of PMIC - LED Drivers. Within this category, the LM3642TLE-LT/NOPB is a current-sensing, cost-effective linear regulator for driving high-power LEDs.

The LM3642TLE-LT/NOPB can provide an efficient means of controlling high-power LEDs. With its efficient linear-mode regulation and low quiescent current, the LM3642TLE-LT/NOPB can achieve an efficiency of up to 90%, reducing power consumed and saving money on overall costs. This makes it ideal for applications such as indoor and outdoor lighting. The LM3642TLE-LT/NOPB also offers protection features such as thermal shutdown, over-current protection and open LED protection, making it more reliable than other LED drivers.

The LM3642TLE-LT/NOPB is a two-terminal current-sensing linear regulator, utilizing a true linear regulation to deliver high output current up to 3.2A. This current-sensing ability helps it to achieve better line regulation (±2%) and load regulation (±5%) than other linear regulator devices. It has an adjustable output voltage and is powered from an external voltage source. The LM3642TLE-LT/NOPB can be operated from an input voltage of 3V to 36V, and the external control voltage can be set between 1V and 8V. In operation, the LM3642TLE-LT/NOPB uses a precision reference voltage to ensure accuracy and stability. The output of the device is regulated by sensing the current flowing through the external sense resistor. When the output voltage reaches a certain value, the LM3642TLE-LT/NOPB will reduce the amount of current being delivered, thus maintaining the output voltage.

The LM3642TLE-LT/NOPB can be used in a number of applications including LED street lighting, LED signs and displays, LED flashlights, LED lighting panels, and LED safety lights. It is also suitable for automotive LED headlamps, LED accent lights, LED work lamps, and LED decorative lighting. With its high efficiency, low quiescent current, protection features, and excellent line and load regulation, the LM3642TLE-LT/NOPB provides an efficient means of controlling high-power LEDs. Its broad range of input and output voltages makes it suitable for a wide range of applications.
