Texas Instruments TPS54373 3V to 6V Input, 3A Synchronous Step-Down SWIFT? Converter for Prebiased Outputs TPS54373PWPRG4

The TPS54373 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 60-m,Ѷ MOSFET switches that enhance efficiency, making it suitable for low-voltage, high-density distributed power systems. The output voltage is adjustable down to 0.9V with an accuracy of 1.0%, allowing for flexibility in various applications. This converter operates at a fixed PWM frequency of 350 kHz or 550 kHz, with the option for adjustable frequencies between 280 kHz and 700 kHz, and can be synchronized to 700 kHz. It includes protective features such as peak current limit and thermal shutdown, ensuring reliable operation. The TPS54373 is particularly well-suited for point-of-load regulation in high-performance DSPs, FPGAs, ASICs, and microprocessors, as well as in broadband and networking applications. The device is housed in a thermally enhanced 20-pin HTSSOP package, which helps reduce board area and component count. It is rated for operation over a temperature range of -40¬8C to 85¬8C, making it suitable for a variety of environmental conditions.
