The Texas Instruments TPS5430DDAR is a versatile DC/DC switching regulator designed for step-down (buck) conversion. It features a wide input voltage range from 5.5V to 36V, allowing for flexible power supply designs. This device can deliver up to 3A of continuous output current, with a peak capability of 4A.
The output voltage is adjustable down to 1.23V with an initial accuracy of 1.5%. The integrated 100mΩ MOSFET switch contributes to high efficiency, reaching up to 95%. A fixed switching frequency of 500kHz is utilized, which helps in reducing the size of external filter components.
System protection is provided through overcurrent limiting, overvoltage protection, and thermal shutdown features. The TPS5430DDAR operates within a junction temperature range of -40°C to 125°C. It is available in a thermally enhanced 8-pin SO PowerPAD™ integrated circuit package, suitable for surface mount applications.
