The Texas Instruments TPS54340BDDA is an active step-down DC/DC converter designed for power management applications. It accepts an input voltage range from 4.5V to 42V, with an absolute maximum rating of 45V. The device can deliver a continuous output current of up to 3.5A, with a minimum peak inductor current limit of 4.5A. The output voltage is adjustable, with a minimum of 0.8V and a maximum of 41.1V.
This converter utilizes current mode control and operates with a switching frequency adjustable from 100kHz to 2.5MHz. Key features include Enable, Frequency synchronization, Light Load Efficiency, Over Current Protection, and adjustable UVLO. It boasts a low quiescent current of 146µA and a shutdown current of 2µA. The internal voltage reference is 0.8V with 1% accuracy.
The TPS54340BDDA is housed in an 8-pin SO PowerPad package, suitable for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ). The device is designed for efficient power conversion in various electronic systems requiring a stable and adjustable output voltage from a higher input voltage source.
