The TPS54680QPWPRQ1 is a highly-integrated, automotive-grade, synchronous buck converter designed by Texas Instruments to meet the rigorous demands of automotive power supply applications. This efficient step-down converter is capable of delivering up to 6A of continuous output current with excellent load and line regulation.

With an input voltage range of 3V to 6V, the TPS54680QPWPRQ1 is versatile enough to handle a variety of automotive power rails, making it ideal for infotainment systems, advanced driver assistance systems (ADAS), and other in-vehicle applications that require a stable and reliable power source.

The device features integrated MOSFETs which enhance its efficiency and reduce the external component count, thereby simplifying the design and saving space on the PCB. The TPS54680QPWPRQ1 supports a switching frequency range of 100 kHz to 600 kHz, which can be adjusted via an external resistor or synchronized to an external clock for noise-sensitive applications.

Protection features are paramount in automotive applications, and the TPS54680QPWPRQ1 does not disappoint. It includes under-voltage lockout (UVLO), thermal shutdown, and over-current protection to safeguard the system under abnormal conditions. Additionally, the device is qualified for automotive applications as it meets the AEC-Q100 Grade 1 standard, ensuring reliable performance over a wide temperature range of -40°C to +125°C.

The TPS54680QPWPRQ1 also boasts a power-good output that provides a system-ready signal once the output voltage reaches its regulated level, enabling a controlled start-up sequence for the connected electronics. This feature is especially useful in complex automotive systems where multiple power domains must be carefully managed.

Offered in a 28-pin HTSSOP PowerPAD™ package, the TPS54680QPWPRQ1 minimizes thermal resistance, allowing for better heat dissipation and improved performance in thermally challenging environments. Whether for powertrain systems, body electronics, or sensor interfaces, this robust converter is designed to provide a stable power solution in the demanding automotive sector.
