Introducing the LTC1517CS5-5#TR from Linear Technology

The LTC1517CS5-5#TR is a high-performance, step-up DC/DC converter designed to provide a fixed 5V output from an input voltage range of 1.5V to 5.5V. This makes it an ideal choice for battery-powered applications where extending battery life is crucial. The device is housed in a compact SOT-23 package, making it suitable for space-constrained applications.

One of the key features of the LTC1517CS5-5#TR is its high efficiency, which can reach up to 90%. This is achieved through an internal synchronous rectifier and optimized switching frequencies, which also help to reduce the size of external components. The converter operates in a Burst Mode® which ensures low quiescent current, further enhancing battery life when the load is light.

The device also includes a shutdown feature that reduces the supply current to less than 5uA, providing an additional power-saving mode for extended battery operation. This is particularly useful in portable devices that require long standby times.

For design flexibility, the LTC1517CS5-5#TR does not require the use of an external diode, which simplifies the design and reduces the overall bill of materials. With its internal power switch and Schottky diode, it can deliver up to 100mA of continuous output current, depending on input voltage and load conditions.

Protection features are also embedded in the LTC1517CS5-5#TR to ensure the longevity and reliability of the application. These include thermal shutdown and current limiting to protect the device and the load under abnormal conditions.

Overall, the LTC1517CS5-5#TR is a versatile, efficient, and reliable solution for a wide range of applications, including handheld devices, GPS units, and portable medical equipment. Its small footprint and high level of integration make it an excellent choice for designers looking to maximize performance while minimizing space and component costs.

With the LTC1517CS5-5#TR, Linear Technology continues to demonstrate its commitment to providing innovative power management solutions that meet the needs of modern electronic devices.
