PMIC - LED Drivers are electronic devices used to satisfy the ever growing demands of the displays, digital signage, and backlighting industry. They provide a reliable, high efficiency solution for powering LEDs and controlling the electrical characteristics of the LED light source. The LT3756EUD-1#PBF is a member of the PMIC - LED Drivers family and it is developed to fill the need for ultra-high efficiency and low power when driving LEDs.

The LT3756EUD-1#PBF is a highly efficient white LED driver for small and medium size general-purpose LCD panels. Its main feature is that it does not need an additional transformer and simplifies the design of lighting systems. This LED driver IC is designed for applications such as small LCD displays, digital signage, and backlighting, and can deliver up to 100mA of continuous current at 12V. It also features a maximum output power of 200mW and is capable of operating at voltages up to 18V.

The LT3756EUD-1#PBF is a 14-pin, dual-output CMOS IC which consists of an oscillator, current sense and regulation, dual current output, and power stages. The oscillator creates a sinusoidal waveform, which is used to sense the current in the LED strings. The current sense and regulation system monitors the current in the LED string and adjusts the oscillator frequency accordingly, to ensure that the LEDs are being driven at the required current. The dual current output system controls each LED string independently and is configured to ensure that the LED current does not exceed the maximum specified level.

The power stages of the LT3756EUD-1#PBF are responsible for supplying the LED current. The IC includes two switch-mode power stages which operate in parallel to increase efficiency and reduce the dissipation of power loss while driving the LED strings. This reduces the overall power loss and increases the overall efficiency of the system.

The LT3756EUD-1#PBF also includes several additional features, such as overtemperature protection, overvoltage protection, undervoltage lockout protection, and current foldback protection. It also provides an adjustable low power shutdown mode, allowing the system to enter into a low power state when the LED current is low. This feature helps to increase the overall efficiency of the system.

The LT3756EUD-1#PBF is an ideal choice for applications where ultra-high efficiency and low power are required when driving LEDs. Its combination of power efficiency, high current output, and protection features make it an optimal choice for a wide range of applications. It is available in ts industry-standard 14-pin DIP, SOIC, and MSOP packages, making it a highly versatile solution for various design needs.
