TPS5450QDDARQ1 TI Switching Regulator | 8-SO-POWERPAD | 5A, 4.5V-36V

Product Overview

The TPS5450QDDARQ1 is a high-output-current, step-down (buck) switching regulator from Texas Instruments, designed for automotive and industrial applications. It integrates a 5A, 36V power MOSFET and operates at a fixed switching frequency of 500 kHz. The device is housed in an 8-pin SO PowerPAD package, which provides excellent thermal performance. With a wide input voltage range of 4.5V to 36V, it is suitable for regulating power from various sources, including unregulated supplies and batteries. The TPS5450QDDARQ1 features internal compensation, making it easy to use with minimal external components.
