PMIC - LED Drivers are an integral part of the power management integrated circuit (PMIC) family. The LT3909IMSE#TRPBF is a PMIC – LED Drivers designed by Linear Technologies. This integrated circuit designed specifically to drive high-brightness LEDs. It is a member of Linear’s family of light-management products, which are designed to provide a user experience that is both reliable and energy efficient.

LT3909IMSE#TRPBF Application Fields

The purpose of this device is to control the current of LED devices independently. It offers seven LED channels with a maximum LED current of 4A. This high current makes it suitable for applications where a large number of LEDs are to be driven, such as commercial lighting and automotive lighting applications. It also provides a wide range of analog and digital control options, allowing the user to adjust the current brightness of the LED output according to their needs.

The LT3909IMSE#TRPBF is also suitable for applications where high speed dimming is required, such as cinema screens, portable projectors, or large-scale conference and display systems. In addition, its programmable current control makes it suitable for situations where the current needs to be changed constantly, such as when changing the color of the display or fading images and video.

LT3909IMSE#TRPBF Working Principle

The LT3909IMSE#TRPBF utilizes an advanced current-regulation design to control the current of each of the seven LED channels independently. It has a low operating temperature, which helps to ensure reliability and consistency of the LED output. The LED Drivers also feature programmable LED brightness control, allowing the user to adjust the brightness according to their specific needs.

The device is equipped with advanced hot-swap protection, which helps to ensure protection when driving large amounts of LEDs or when connecting multiple LEDs in cascade. This protection prevents the device from overheating or damaging the LEDs when rapidly connecting or disconnecting from the power source.

The LT3909IMSE#TRPBF also supports up to six switch-mode buck or boost converters. This enables the user to provide an adjustable LED output using different LED configurations. In addition, the device features programmable LED channels, allowing users to independently control the LED brightness on various LED strings.

The LT3909IMSE#TRPBF incorporates several additional features, such as a digital dimming interface, multiple dimming curve options, and many more. The digital dimming interface allows the user to control the LED drivers remotely, providing convenient control. Furthermore, the multiple dimming curve options enable the user to adjust the LED output via pulse-width modulation (PWM) or digital control (DC).
