The TPS54340QDDARQ1 from Texas Instruments is an automotive-qualified step-down DC-DC converter designed for a wide input voltage range of 4.5V to 42V, capable of delivering up to 3.5A of output current. This device operates in current mode and offers an adjustable switching frequency from 100kHz to 2.5MHz, with the ability to synchronize to an external clock.
Key features include high efficiency at light loads with Eco-mode, a low quiescent current of 146µA, and a shutdown current of 2µA. It also provides adjustable UVLO voltage and hysteresis, a 0.8V internal voltage reference with 1% accuracy, and a 92mΩ high-side MOSFET. The converter is suitable for applications requiring stable voltage regulation over a broad input range.
Packaged in an 8-pin SO PowerPad (HSOIC) with dimensions of 4.9 mm x 6 mm, the TPS54340QDDARQ1 is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 125°C and a junction temperature range of -40°C to 150°C. This part is AEC-Q100 qualified.
