The LT3486IFE#TRPBF is a high current LED driver specifically designed for wide input voltage and high brightness LED applications. It is a cost effective alternative to traditional LED drivers, providing a highly efficient, temperature compensated solution for continuous LED operation up to 8 amps. In addition, the LT3486IFE#TRPBF utilizes a unique current regulation loop and is capable of dimming from 0-100 percent.
The LT3486IFE#TRPBF is a monolithic high-efficiency switching regulator used for driving LEDs in a power-controlled circuit. It has an integrated FET, PWM control and current regulation loop, which allow it to be used in applications that require high efficiency, dimmability and tight current regulation. The device is able to source as much as 8.5A of continuous current to a single LED string. The LT3486IFE#TRPBF utilizes a wide input voltage supply range, supporting up to 45V, making it suitable for automotive, industrial and architectural lighting applications.
The working principle of LT3486IFE#TRPBF is that the input voltage is applied across the inductor and the current in the inductor is sensed by the shunt resistor. This sensed current is then compared against the desired LED drive current by the current loop. The output voltage is then adjusted to regulate the current in the system accordingly. The pulse-width modulation (PWM) of the switch controls the output current, with higher duty cycles resulting in higher LED currents. The system also features a temperature compensation loop, which helps to maintain the LED’s brightness over the life of the LED driver. This loop is also used to protect the LED from running at dangerously high temperatures.
The LT3486IFE#TRPBF is a cost-effective and efficient LED driver solution, making it a great choice for applications that require high current, dimming and tight current regulation. Its wide supply voltage range, high internal switching frequency, and temperature compensation loop make it suitable for a wide range of applications, including automotive, industrial and architectural lighting. This LED driver is highly suitable for environments that have a wide operating temperature range and require continuous operation.
