TPS22917DBVR – TEXAS INSTRUMENTS

The TPS22917DBVR is a Texas Instruments single-channel, 4A synchronous buck converter housed in a compact, 16-pin QFN package (4x4mm). Designed for high-efficiency power conversion in space-constrained applications, it operates from a wide input voltage range of 4.5V to 18V, delivering a precisely regulated output voltage. Its internal synchronous rectification minimizes conduction losses, achieving efficiencies exceeding 90% at typical loads. The device incorporates features crucial for robust operation, including a soft-start function to limit inrush current, overcurrent protection, and thermal shutdown. Its programmable output voltage via external resistors allows flexibility in system design. The TPS22917DBVR is ideally suited for powering high-current loads in portable devices, industrial controls, and automotive applications where efficiency and compact size are paramount. Its small footprint and high efficiency make it a superior alternative to larger, less efficient linear regulators or discrete solutions, providing a significant advantage in thermal management and overall system design optimization. The integrated protection features enhance system reliability, minimizing the need for external components.
