The Texas Instruments TPS5430DDA is a versatile step-down DC/DC converter designed for power management applications. It features a wide input voltage range from 5.5V to 36V, allowing it to accommodate various power sources.
This device can deliver up to 3A of continuous output current and offers an adjustable output voltage down to 1.22V with 1.5% initial accuracy. The integrated 100mΩ MOSFET switch contributes to high efficiency, reaching up to 95%. Key electrical features include overcurrent protection and an enable function.
The TPS5430DDA operates at a fixed switching frequency of 500kHz, which helps in reducing the size of external filter components. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for demanding environments. The converter is housed in a thermally enhanced 8-pin SO PowerPAD package, designed for surface mounting.
System protection is provided through overcurrent limiting, overvoltage protection, and thermal shutdown features. Internal compensation simplifies the external component count, further aiding in design efficiency.
