Linear Technology LTC1517CS5-5#TRMPBF Description

The LTC1517CS5-5#TRMPBF is a high-performance, step-up DC/DC converter designed by Linear Technology, now part of Analog Devices, that is specifically engineered to meet the needs of portable electronic devices. This efficient power solution is ideal for applications that require a fixed 5V output voltage from a lower voltage source, such as single-cell lithium-ion batteries or multiple alkaline/NiCd/NiMH cells.

This device comes in a compact SOT-23 package, making it suitable for space-constrained applications. The LTC1517CS5-5#TRMPBF operates at a switching frequency of 100kHz, allowing the use of small, low-cost inductors and capacitors while still providing solid power conversion efficiency. Its low quiescent current also makes it an excellent choice for battery-powered devices where extending battery life is crucial.

One of the key features of the LTC1517CS5-5#TRMPBF is its low-battery detector, which provides an early warning when the battery voltage falls below a preset threshold, enabling intelligent power management in portable devices. The device also includes a shutdown mode that reduces the supply current to less than 10µA, further conserving battery life when the device is not in use.

Additional features of this step-up converter include thermal shutdown for protection against overheating and a current limit to protect the device under over-current conditions. Its automatic shifting to power-saving Burst Mode operation at light loads significantly improves efficiency, making it an environmentally friendly choice for modern electronic equipment.

Overall, the LTC1517CS5-5#TRMPBF is a reliable and versatile power management solution that delivers consistent performance while its small footprint and low power consumption make it an ideal choice for designers looking to optimize their portable and battery-operated devices.
