Texas Instruments TPS54380 3V to 6V Input, 3A Synchronous Step-Down Converter for Sequencing TPS54380PWPG4

The TPS54380 is a synchronous step-down converter designed for input voltages ranging from 3V to 6V and capable of delivering up to 3A of output current. It features integrated 60-m,Ѷ MOSFET switches, which contribute to high efficiency in power conversion. The device supports power-up and power-down sequencing through its TRACKIN pin, making it suitable for applications requiring precise voltage regulation during startup and shutdown. This converter operates at a fixed frequency of 350 kHz or can be adjusted between 280 kHz and 700 kHz, providing flexibility in design. It includes essential protection features such as peak current limit and thermal shutdown, ensuring reliable operation under various conditions. The TPS54380 is housed in a thermally enhanced 20-pin TSSOP package, which minimizes the need for additional heatsinking and reduces overall board area. Applications for the TPS54380 include low-voltage, high-density distributed power systems, point-of-load regulation for high-performance DSPs, FPGAs, ASICs, and microprocessors, as well as use in broadband, networking, and optical communications infrastructure.
