TPS54325TPWPRQ1 Description

Short technical summary and product information.

The TPS54325TPWPRQ1 from Texas Instruments is a high-performance synchronous buck converter designed for automotive applications. It features D-CAP2 mode control, enabling extremely fast transient response without external components and supporting low equivalent series resistance (ESR) output capacitors like POSCAP or SP-CAP, as well as ultra-low ESR ceramic capacitors.

 

This converter operates with a wide VCC input voltage range of 4.5V to 18V and a VIN range of 2.0V to 18V. The output voltage is programmable between 0.76V and 5.5V, with a maximum output current of 3A. It boasts a high switching frequency of 700kHz, integrated FETs with low on-resistance (120mΩ high-side, 70mΩ low-side), and high efficiency, drawing less than 10μA at shutdown.

 

The TPS54325TPWPRQ1 is housed in a 14-pin HTSSOP package and is designed for operation in ambient temperatures ranging from -40°C to 105°C. It includes features such as adjustable soft-start, pre-biased soft-start, and a power-good output, making it suitable for various low-voltage system power bus regulation needs.
