TPS54332DDAR Step-Down Converter | 3.5-28V | 3.5A | 1MHz | SO-8 PowerPAD Package | Texas Instruments

The TPS54332DDAR is a 28V, 3.5A non-synchronous buck converter from Texas Instruments (TI), integrating a low on-resistance (80mΩ) high-side MOSFET. Using current-mode control with internal slope compensation, it simplifies external compensation design and reduces component count while allowing the use of ceramic output capacitors. Its key advantage is the Eco-mode™ pulse-skipping feature, which automatically activates at light loads to significantly improve efficiency; the shutdown quiescent current is only 1µA typical, making it ideal for battery-powered applications. The device also features programmable UVLO threshold, adjustable slow-start to limit inrush current, overvoltage transient protection, and comprehensive protection including cycle-by-cycle current limit, frequency foldback, and thermal shutdown. Housed in a thermally enhanced 8-pin SOIC PowerPAD package (4.9×6.0mm), it operates over a junction temperature range of -40°C to +150°C. It is ideal for set-top boxes, CPE equipment, LCD displays, industrial and car audio power supplies, and 5V/12V/24V distributed power systems.
