LT1615IS5#TRMPBF Step-Up DC/DC Converter

The LT1615IS5#TRMPBF is a high-performance step-up DC/DC converter from Linear Technology, designed to meet the needs of a wide range of applications requiring efficient voltage boosting. The device is housed in a compact SOT-23 package, making it ideal for space-constrained applications.

This versatile converter operates from an input voltage as low as 1.2V, making it suitable for single-cell, multi-cell, or other low voltage power sources. The LT1615IS5#TRMPBF can deliver output voltages up to 34V, and its internal 36V, 350mA switch allows for output currents up to tens of milliamps depending on the input voltage and the output voltage settings.

The LT1615IS5#TRMPBF features a high switching frequency of 1.2MHz, which allows for the use of small, low-cost capacitors and inductors, reducing the overall footprint and component cost of the power supply design. Additionally, its high frequency operation can help in avoiding critical noise-sensitive frequency bands, such as AM radio bands, making it suitable for noise-sensitive applications.

Another key feature of the LT1615IS5#TRMPBF is its low quiescent current, which makes it an excellent choice for battery-powered devices. The quiescent current is only 20uA, which helps to extend battery life when the device is in operation, and less than 1uA in shutdown mode.

The device also includes several built-in protection features such as current limiting and thermal shutdown, ensuring reliable operation under a variety of conditions. The thermal protection automatically reduces the switch duty cycle when the internal temperature exceeds the preset threshold, protecting the device from overheating.

Overall, the LT1615IS5#TRMPBF is a robust, efficient, and versatile step-up converter that offers a compact solution for boosting voltages in a variety of electronic products, including handheld devices, GPS units, and portable medical equipment.
