TPS57140QDRCRQ1 Automotive Step-Down Converter by Texas Instruments

The TPS57140QDRCRQ1 is a highly efficient, small-sized, automotive-grade, synchronous step-down converter designed by Texas Instruments to meet the rigorous standards of the automotive industry. This advanced power management integrated circuit (IC) is ideal for use in automotive applications that require a low-power, high-performance power supply solution.

With an input voltage range of 3.5V to 42V, the TPS57140QDRCRQ1 is capable of withstanding the fluctuations and transients commonly found in automotive power systems, making it an excellent choice for powering advanced driver-assistance systems (ADAS), infotainment systems, and other in-vehicle electronics. The device is designed to deliver a continuous output current of up to 1.5A, while its peak current capability can handle higher transient loads, ensuring reliable operation even under demanding conditions.

The TPS57140QDRCRQ1 features an adjustable output voltage that can be set from 0.8V to 17V, providing design flexibility to match the voltage requirements of various loads. Its high-efficiency operation is achieved through the use of synchronous rectification and a low quiescent current, which also helps to reduce thermal dissipation and extend battery life.

The converter operates at a fixed switching frequency of 2.1MHz, which allows the use of small external components, resulting in a compact power supply design. Additionally, its frequency synchronization capability can be used to manage electromagnetic interference (EMI), a critical consideration in automotive environments.

For safety and reliability, the TPS57140QDRCRQ1 incorporates a range of protection features, including overcurrent protection, overvoltage protection, thermal shutdown, and undervoltage lockout. The device is available in a small 10-pin SON package, which is suitable for space-constrained applications.

With its robust performance, small form factor, and comprehensive protection features, the TPS57140QDRCRQ1 from Texas Instruments is a versatile and reliable choice for modern automotive power supply designs.
