Analog Devices Inc. Presents the LT3990EDD#TRPBF

The LT3990EDD#TRPBF is a high-performance DC/DC converter brought to you by Analog Devices Inc., a leader in the design and manufacturing of analog, mixed signal, and DSP integrated circuits. This robust and efficient power solution is designed to meet a wide range of applications, including industrial, automotive, and telecommunications systems.

This step-down converter operates over a wide input voltage range of 4V to 20V, making it versatile for various power supply scenarios. It is capable of delivering up to 550mA of continuous output current to a regulated voltage as low as 0.79V, which is essential for powering low-voltage microprocessors and other digital logic devices.

The LT3990EDD#TRPBF comes in a compact, thermally enhanced 10-lead DFN package with a 3mm x 3mm footprint. This small form factor is particularly advantageous for space-constrained applications. The device also features an internal 1.5A switch, further reducing the need for external components and simplifying the design process.

One of the key attributes of this DC/DC converter is its high efficiency, which can be up to 93%. This is achieved through its Burst Mode® operation, which reduces quiescent current to only 2.8μA during no load conditions, thereby significantly extending battery life in portable applications.

Moreover, the LT3990EDD#TRPBF is designed with the user in mind, featuring a range of built-in protection features. These include thermal shutdown, reverse battery protection, current limiting, and the ability to withstand reverse input voltages, ensuring reliable performance under various conditions.

To accommodate different design requirements, the LT3990EDD#TRPBF also offers programmable frequency from 200kHz to 2.4MHz or it can be synchronized to an external clock, providing design flexibility and the ability to optimize component size and performance.

Overall, the LT3990EDD#TRPBF is an excellent choice for designers looking for a high-efficiency, low-quiescent current, and versatile power solution that comes in a package suitable for space-constrained applications.
