LT3590EDC#TRPBF

The LT3590EDC#TRPBF is a high efficiency, robust current mode step-up controller that can be used to power a multiple of LED strings in series with series voltage up to 110V. It has built in diagnostics and integrated protection from events such as over temperature, over current and short circuit, making it ideal for low voltage applications.

The LT3590EDC#TRPBF is based on a frequency modulation adaptive on time architecture that continuously adjusts the switching frequency and its switching duty cycle to optimize the inductor ripple current. This allows it to optimize the efficiency and ripple current in a wide range of dual inductor configurations.

The controller features an adjustable current sense voltage and an adjustable maximum switch on-time. The adjustable minimum off time also allows users to optimize the operating parameter and gives designers the flexibility to meter the switching frequency and duty cycle in wide variation of operating conditions.

The LT3590EDC#TRPBF operates off an input voltage of 4.5V to 38V and can be used to drive dual inductor topologies such as the Two Transistor Forward and the Two Transistor Reverse configuration. This makes it suitable for DC-DC LED drivers applications including LED lighting, automotive lighting, automotive headlights and automotive tail lights.

The LT3590EDC#TRPBF is protected and operated by its built-in over temperature protection feature. The operating temperature range is specified from -40C to 125C. Its sixteen pins exposed Pad package makes it easy to mount and allows the designer to connect the external components optimally.

The LT3590EDC#TRPBF is a single device pre-configured to accept the most common LED string configurations. The main advantage of using this device is that it not only offers maximum efficiency and robust protection, but also a great level of flexibility with its versatile built in parameters.

In conclusion, the LT3590EDC#TRPBF is an ideal driver IC for medium to high power LEDs applications requiring a high level of performance and protection. It is available in a sixteen pins exposed pad package and offers great flexibility and maximum efficiency.
