TPS54340QDDARQ1 TI DC-DC Converter | 8-SO-POWERPAD | 3.5V-42V, 3.5A

Product Overview

The TPS54340QDDARQ1 is a high-performance, automotive-grade step-down (buck) DC-DC converter from Texas Instruments. It integrates a low RDS(on) high-side MOSFET and operates over a wide input voltage range of 3.5V to 42V, making it suitable for 12V, 24V, and 48V automotive and industrial power systems. The device delivers up to 3.5A continuous output current with excellent efficiency and thermal performance. Housed in an 8-pin SO PowerPAD package, it offers enhanced thermal dissipation for reliable operation in harsh environments.
