LT3599IFE#TRPBF

LT3599IFE#TRPBF is a multi-functional integrated Power Management Integrated Circuit (PMIC) belonging to the LED Drivers family, specifically developed to drive LEDs with high efficiency while at the same time providing a low system component count to reduce the cost and weight of the overall project. It integrates both a DC/DC switching regulator as well as an advanced automatic dimming control for driving LEDs, providing a cost-effective solution for a wide range of applications.

The LT3599IFE#TRPBF output current can be regulated using the internal dimming control, or with external PWM dimming control. The built-in load switch ensures that the output current is accurately regulated, providing a low ripple current, which helps extend the life span of LEDs. It also provides an output voltage regulation with an internal reference voltage, as well as protection features such as over-temperature and over-current shutdown.

This product is suitable for controlling and driving LEDs in various general lighting, automotive, consumer and industrial applications such as LED street lighting, automotive headlamps and interior lighting, LED signage, and LED illumination. It features a wide 4.5V-36V input voltage range, output current of up to 1.6A and an adjustable output current of up to 4A.

LT3599IFE#TRPBF works on a buck-boost principle to drive multiple types of LEDs with high efficiency. The buck-boost topology is designed to provide a high step-down ratio with low current ripple over a wide input voltage range. The built-in dimming control also enables the LED driver to dim LEDs from 50% to full brightness without any extra external components. This also helps in increasing the lifetime of the LEDs and reducing maintenance costs.

The output voltage of the LT3599IFE#TRPBF can be configured via the input voltage. An internal high voltage MOSFET switch enables the high efficiency buck-boost operation. This switch is used to deliver the current to the LEDs efficiently. An external compensation is also provided to maintain constant current over a wide range of input and output voltages.

Furthermore, the LT3599IFE#TRPBF incorporates additional features such as an over-temperature protection, as well as an adjustable soft-start circuit that helps to limit the inrush current. The adjustable-current limit feature allows the user to set the current limit based on their system requirements. The built-in short-circuit protection also offers improved performance by preventing overload and short-circuit conditions.

To sum up, LT3599IFE#TRPBF is an ideal solution for driving multiple LEDs with a wide input voltage range and high efficiency. Its advanced protection features including over-temperature protection, adjustable-current limit, soft-start circuit, and built-in dimming control make it an ideal choice for a variety of applications.
