The LTC3454EDD#TRPBF is a highly integrated step up DC/DC converter that is designed for driving high power LEDs for a variety of applications. The device is fully integrated within a single package and provides an efficient solution for driving high power LEDs with maximum illumination and minimum power consumption. It is specifically designed for use in applications that require high output power and performance.

The LTC3454EDD#TRPBF is an intelligent step-up converter that can be used to power up to 60V LED chains with a single DC input source. The device is configured for a standard DC source, such as a battery, wall adaptor or USB port, and is capable of providing a constant current output of up to 0.85A. The output current is adjustable using an external RSET resistor, allowing the user to customize the LED performance.

The main features of the LTC3454EDD#TRPBF include power saving efficiency by using PWM dimming control, over current protection, and thermal shutdown circuitry. The device also supports synchronous rectification to further reduce power loss and improve system stability. The on-board logic circuitry is designed to manage the LED lighting system and provide a safe and reliable power supply. In addition, the device features over-voltage protection with an adjustable threshold, as well as short circuit and reverse voltage protection.

The LTC3454EDD#TRPBF can be configured in various topologies depending on the application requirements. In a non-isolated buck/boost configuration, the LED string is driven by the step-up DC-DC converter, which in turn is powered by a single DC source. The device is also suitable for applications that require a current-source output, such as automotive-lighting systems.

The working principle of the LTC3454EDD#TRPBF is based on the simple principle of using a DC-DC converter to step up or down the input voltage to the desired output voltage. The device features a low-dropout (LDO) linear regulator, which steps up the voltage from the input source to the output voltage. The current supplied by the device is controlled by the external RSET resistor, which sets the current output limit. The PWM dimming control feature helps to save power by switching the power supply on and off at frequencies higher than the human eye can detect.

The LTC3454EDD#TRPBF is an ideal choice for designing high power LED lighting systems that require highly efficient, easy to use, and reliable operation. The device is widely used in automotive lighting, industrial lighting, and general lighting applications. It is a cost-effective solution for meeting the lighting demands of today’s high-power LED applications.
