TPS5431DDAG4 Description

Short technical summary and product information.

The Texas Instruments TPS5431DDAG4 is a versatile step-down (buck) DC/DC switching regulator designed for power management applications. It supports an adjustable output voltage down to 1.22V with an initial accuracy of 1.5% and can deliver up to 3A of continuous output current (4A peak).

 

This device features a wide input voltage range from 5.5V to 23V, making it suitable for various power supply designs. The integrated 100mΩ MOSFET switch contributes to high efficiency, reaching up to 95%. A fixed switching frequency of 500kHz allows for smaller filter component sizes.

 

System protection is provided through overcurrent limiting, overvoltage protection, and thermal shutdown. The TPS5431DDAG4 operates within a junction temperature range of -40°C to 125°C and is available in a thermally enhanced 8-pin SO PowerPAD™ package, suitable for surface mounting.

 

Internal compensation simplifies the external component count, and features like input voltage feedforward improve line regulation and transient response. This makes the TPS5431DDAG4 a robust choice for designs requiring efficient and reliable voltage conversion.
