Introducing the LTC3526LBEDC from Linear Technology

The LTC3526LBEDC is a high-efficiency, synchronous step-up DC/DC converter that is ideal for powering small, battery-operated devices. Manufactured by Linear Technology, a leader in the design and production of high-performance analog integrated circuits, this product is designed to provide a compact and reliable power solution for portable electronics.

This efficient converter is capable of starting up from an input voltage as low as 0.85V and can continue to operate down to 0.5V once started. This feature makes the LTC3526LBEDC particularly suitable for applications that utilize single-cell alkaline, NiMH, or NiCd batteries. The device can deliver up to 400mA of continuous output current at a 3.3V output with a 1.2V input, ensuring that your devices have the power they need to function effectively.

The LTC3526LBEDC comes in a compact, low-profile (0.74mm) 6-pin 2mm x 2mm DFN package, making it an excellent choice for space-constrained applications. Its small size does not compromise its performance, as it includes an integrated synchronous rectifier, which significantly improves efficiency compared to traditional solutions that use diodes. This leads to extended battery life, which is critical for portable devices.

Furthermore, the LTC3526LBEDC features a fixed frequency, current mode operation which provides excellent line and load regulation, as well as low output ripple. The device also has internal soft-start to limit inrush current during startup, reducing stress on the battery and prolonging its life. Additionally, it includes undervoltage lockout, thermal shutdown, and short-circuit protection, ensuring safe operation under various conditions.

Whether you're designing power supplies for handheld medical devices, wireless sensors, or any other portable application, the LTC3526LBEDC from Linear Technology offers a reliable and efficient solution that minimizes board space without sacrificing performance.
