Texas Instruments TPS54313 3V to 6V Input, 3A Synchronous Step-Down SWIFT? Converter with 1.5V Output TPS54313PWPG4

The TPS54313PWPG4 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 provides a fixed output voltage of 1.5V with an initial accuracy of 1.0%. The device features integrated 60-mOc MOSFET switches, which contribute to high efficiency during operation. This converter is internally compensated, simplifying the design process by reducing the number of external components required. It supports a wide range of PWM frequencies, including fixed frequencies of 350 kHz and 550 kHz, as well as adjustable frequencies from 280 kHz to 700 kHz. The TPS54313 includes several protection features such as undervoltage lockout, peak current limit, and thermal shutdown, ensuring reliable operation in various applications. The device is housed in a thermally enhanced 20-pin HTSSOP package, which helps minimize board area and eliminates the need for bulky heatsinks. It is suitable for low-voltage, high-density systems, point-of-load regulation for high-performance processors, and applications in broadband and networking infrastructure.
