Texas Instruments TPS5430-Q1 Automotive Catalog 5.5V to 36V, 3-A Step-Down Converter TPS5430QDDARQ1

The TPS5430-Q1 is a step-down converter designed for automotive applications, capable of handling input voltages from 5.5V to 36V and delivering up to 3A of continuous output current, with a peak capability of 4A. It features high efficiency, reaching up to 95%, thanks to its integrated 100m,Ѷ MOSFET switch. The output voltage is adjustable down to 1.22V with an initial accuracy of 1.5%. This device includes internal compensation to reduce the need for external components, a fixed switching frequency of 500kHz for compact filter designs, and enhanced transient response through input voltage feed-forward. Protection features include overcurrent limiting, overvoltage protection, and thermal shutdown, ensuring reliable operation across a wide temperature range of -40¬8C to 125¬8C. The TPS5430-Q1 is packaged in a thermally enhanced 8-pin SOIC PowerPAD format, facilitating efficient thermal management. It is suitable for applications such as car audio power supplies, high-power LED drivers, and battery chargers. Additionally, Texas Instruments provides design support through evaluation modules and the WEBENCH Power Designer tool.
