The Texas Instruments TPS61253AYFFR is a high-performance boost converter IC. It is designed to step up voltage efficiently, operating from an input voltage range of 2.3V to 5.5V. The device offers fixed output voltages, with options including 4.5V, 4.7V, 5.0V, 5.2V, and 5.25V, and features a typical output current capability of 1.5A continuously at 5V output and 3V input.
This boost converter operates at a switching frequency of 3.8MHz, contributing to its compact design and efficiency. It integrates synchronous rectification for improved performance and features like light-load efficiency and load disconnection during shutdown. The TPS61253AYFFR is housed in a small 9-DSBGA package, making it suitable for space-constrained applications. It is designed for surface mounting and operates within a temperature range of -40°C to 85°C.
Key electrical characteristics include a switch current limit of 4A (typical) and a soft-start time of 600µs. The output voltage accuracy is typically ±2%. The device also includes protection features such as hiccup-mode short protection and thermal shutdown, enhancing reliability in various operating conditions.
