Texas Instruments Buck 5A 60V 58.8V Step-Down DC-DC Converter IC TPS54561QDPRRQ1

The TPS54561QDPRRQ1 is a 60V, 5A step-down voltage regulator designed for automotive applications, featuring an integrated high-side MOSFET. It complies with ISO 7637 standards, allowing it to withstand load dump transients up to 65V. The device operates with a wide input voltage range of 4.5V to 60V and offers a low quiescent current of 152¬µA, which drops to 2¬µA in shutdown mode. It supports Eco-mode,Ñ¢ for high efficiency under light load conditions and features adjustable switching frequency from 100kHz to 2.5MHz, enabling optimization for efficiency or component size. The TPS54561QDPRRQ1 includes internal undervoltage lockout set at 4.3V, soft-start capabilities, and power-good output monitoring. It is housed in a compact 10-pin WSON package, suitable for applications such as vehicle accessories, USB charging ports, and onboard power systems. The operating temperature range is from -40¬8C to 125¬8C, making it suitable for harsh environments.
