The Texas Instruments TPS563219DDFT is a highly integrated, easy-to-use synchronous step-down (buck) converter. It is designed for applications requiring efficient power conversion with a compact footprint.
This regulator features a wide input voltage range of 4.5V to 17V and can deliver up to 3A of output current. It operates at a switching frequency of 650kHz, contributing to its small solution size. The TPS563219DDFT offers an adjustable output voltage, with a specified output voltage range from 0.76V to 7V. Key electrical characteristics include a low shutdown current of less than 10µA and a feedback voltage accuracy of 1% at 25°C.
The device is housed in an 8-pin SOT-23-8 (TSOT-23-8) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The synchronous rectification design enhances efficiency by integrating low-resistance FETs.
This component is part of the TPS563219 series, known for its D-CAP2 mode control, which simplifies compensation and enables fast transient response. It includes protection features such as cycle-by-cycle overcurrent limit and hiccup-mode undervoltage protection.
