LTC1514CS8-3.3#TRPBF - Step-Up/Step-Down DC/DC Converter

The LTC1514CS8-3.3#TRPBF is a versatile DC/DC converter IC designed and manufactured by Linear Technology, now part of Analog Devices. It is specifically engineered to provide a constant 3.3V output from a wide input voltage range, making it an ideal choice for battery-powered applications where input voltage can vary significantly.

This step-up/step-down converter operates efficiently with an input voltage range from 2V to 12V, making it suitable for single-cell, multi-cell, or regulated input supplies. The LTC1514CS8-3.3#TRPBF ensures a stable and regulated output even when the input voltage is above, below, or equal to the output voltage, thanks to its seamless transition between buck and boost modes.

The device is housed in an 8-lead SOIC package, providing a compact solution for space-constrained applications. With a fixed output voltage of 3.3V, it simplifies the design process, eliminating the need for external resistors to set the output voltage, which is often the case with adjustable regulators.

Key features of the LTC1514CS8-3.3#TRPBF include its low quiescent current and high efficiency across a wide range of load currents. This is particularly important for portable applications where battery life is critical. Additionally, it offers a low-battery detector that signals when the input voltage falls below a preset threshold, which is invaluable for preventing deep discharge of batteries.

Protection features are also built into the LTC1514CS8-3.3#TRPBF, including current limiting and thermal shutdown, ensuring reliable operation under fault conditions. The device also supports a shutdown mode, reducing the supply current to less than 10µA, which is essential for preserving battery life during periods of inactivity.

Overall, the LTC1514CS8-3.3#TRPBF is a robust, efficient, and easy-to-use power management solution, well-suited for a range of portable electronics, including PDAs, mobile phones, and wireless modems, where consistent power delivery and battery longevity are paramount.
