TPS5430DDAG4 step-down converte 1 Output 3A
The TPS5430DDAG4 is a 3A wide-input-range step-down (buck) converter from Texas Instruments, designed for high-efficiency power management in consumer, industrial, and automotive applications. Housed in a thermally enhanced 8-pin SOIC PowerPAD package, this device integrates a 110mΩ high-side N-channel MOSFET and operates from a wide 5.5V to 36V input voltage range, making it ideal for 12V and 24V distributed power systems. Delivering up to 3A continuous output current (4A peak) with adjustable output voltage down to 1.22V at 1.5% initial accuracy, it achieves up to 95% efficiency at 500kHz fixed switching frequency. The device features internal compensation, voltage feedforward for improved line regulation, and comprehensive protection including overcurrent limiting, overvoltage protection, and thermal shutdown, ensuring reliable operation across the automotive temperature range of -40°C to +125°C.
