TPS54425PWPR Description

Short technical summary and product information.

The Texas Instruments TPS54425PWPR is a highly efficient synchronous step-down (buck) converter designed for various low-voltage applications. It operates with an input voltage range of 4.5V to 18V and can deliver up to 4A of output current. The output voltage is adjustable, ranging from 0.76V to 5.5V, making it versatile for different power management needs.

 

This converter utilizes the D-CAP2™ mode, which enables fast transient response and low output ripple, allowing the use of ceramic output capacitors. Key features include integrated FETs with low on-resistance (65 mΩ high side, 55 mΩ low side), a switching frequency of 700kHz, and low quiescent current of 0.00085A typical. It also includes essential functions like Enable, Power Good, and Soft Start.

 

The TPS54425PWPR is housed in a 14-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). This device is well-suited for applications such as digital TV power supplies, high-definition Blu-ray disc players, networking equipment, and digital set-top boxes.
