TPS54340BDDAR Description

Short technical summary and product information.

The Texas Instruments TPS54340BDDAR is an active step-down DC/DC converter designed for power management applications. It accepts an input voltage range of 4.5V to 42V (45V absolute maximum) and can deliver up to 3.5A of continuous output current.

 

This converter utilizes current mode control and features a high-side MOSFET with a low 92-mΩ resistance. It is designed for high efficiency, particularly at light loads, through its Pulse Skipping Eco-mode™. The device also offers adjustable UVLO, frequency synchronization, and accurate cycle-by-cycle current limiting.

 

Packaged in an 8-pin HSOIC with PowerPAD™, the TPS54340BDDAR has an operating temperature range of -40°C to 150°C. Its low quiescent current of 146µA and shutdown current of 2µA make it suitable for power-sensitive applications. The fixed switching frequency can be synchronized to an external clock, ranging from 100kHz to 2.5MHz.
