TPS562208DDCR - 2A Synchronous Buck Switching Regulator IC, 4.5V–17V Input, SOT-23-6 Package
The TPS562208DDCR from Texas Instruments is a compact and efficient 2A synchronous step-down converter designed to deliver high performance with minimal external components. Operating over a wide input voltage range of 4.5V to 17V, it provides a stable and efficient output voltage suitable for powering low-voltage digital ICs, processors, and sensors in industrial, communication, and consumer applications.
The device integrates high- and low-side MOSFETs and employs the D-CAP2 control scheme, offering a fast transient response while supporting low ESR output capacitors such as polymer or ceramic types. This design eliminates the need for external compensation, simplifying PCB layout and reducing overall solution size. The TPS562208 operates in continuous current mode, ensuring consistent performance under varying load conditions. Additional built-in protections include cycle-by-cycle overcurrent limit, hiccup-mode overcurrent protection, undervoltage protection (UVP), and thermal shutdown (TSD).
