LT3495EDDBDTRPBF - Linear Technology

The LT3495EDDBDTRPBF is a high-performance, adjustable frequency, monolithic step-up DC/DC converter designed by Linear Technology, a brand synonymous with precision, reliability, and innovation in the field of power management integrated circuits. This product is specifically engineered to cater to the needs of small, battery-powered applications where efficient power conversion and compact footprint are of utmost importance.

One of the standout features of the LT3495EDDBDTRPBF is its wide input voltage range, which allows it to operate from inputs as low as 2.5V, making it ideal for single-cell Li-Ion applications, and up to 12V, accommodating a broad spectrum of power sources. The device is capable of delivering a continuous output current up to 350mA, with an output voltage that is adjustable up to 34V, ensuring that it can drive a variety of loads, including multiple white LEDs in series.

The LT3495EDDBDTRPBF employs an internal 1.2A, 40V switch, which facilitates a small external component count, thus reducing the overall solution size—a critical factor for space-constrained applications. The device's fixed frequency, current mode architecture ensures stable operation over a wide range of supply and output voltages, and its frequency can be set between 1.2MHz and 2.2MHz, allowing the use of tiny, low-cost capacitors and inductors.

Additional features include integrated soft-start, which minimizes inrush current during startup, and a high switching frequency that enables the use of small external components. The LT3495EDDBDTRPBF also offers thermal protection and a shutdown function, which reduces the quiescent current to less than 1µA, further enhancing battery life in portable applications.

Available in a small 10-lead (3mm × 3mm) DFN package, the LT3495EDDBDTRPBF is designed to minimize the solution footprint on the PCB, making it an excellent choice for portable and miniaturized electronic devices. Whether you're designing LED drivers, battery-powered equipment, or handheld devices, this versatile step-up converter from Linear Technology is engineered to meet your power management requirements with efficiency and reliability.
