TPS54418RTER Description

Short technical summary and product information.

The Texas Instruments TPS54418RTER is a synchronous step-down buck (switching) voltage regulator designed for high-efficiency power conversion. It can deliver up to 4A of continuous output current and supports an input voltage range from 2.95V to 6V.

 

The output voltage is adjustable from 0.8V to 4.5V, with a voltage reference accuracy of ±1% over temperature. The regulator features a programmable switching frequency from 200kHz to 2MHz, allowing optimization between efficiency and component size. Its internal MOSFETs have a typical on-resistance of 30mΩ, contributing to low conduction losses.

 

The device is housed in a compact 16-pin WQFN package (3mm x 3mm) with an exposed pad for thermal dissipation. It operates over a junction temperature range of -40°C to 150°C, making it suitable for industrial and automotive applications. Typical applications include point-of-load regulation, distributed power systems, and battery-powered devices.
