Texas Instruments TPS54314 3V to 6V Input, 3A Synchronous Step-Down SWIFT? Converter with 1.8V Output TPS54314PWP

The TPS54314PWP is a synchronous buck PWM switching regulator designed for low-input voltage applications, with an input voltage range of 3V to 6V and a maximum output current of 3A. It features a fixed output voltage of 1.8V with an initial accuracy of 1.0%. The device integrates high-efficiency 60-mOc MOSFET switches, which contribute to its performance in terms of efficiency and thermal management. The TPS54314PWP is internally compensated, reducing the need for external components, and offers fast transient response. It operates at a fixed PWM frequency of 550 kHz, with options for adjustable frequencies ranging from 280 kHz to 700 kHz. Additional features include undervoltage lockout, peak current limit protection, and a power-good output for fault signaling. The device is housed in a thermally enhanced 20-pin HTSSOP package, which aids in minimizing board area and eliminating the need for bulky heatsinks. This regulator is suitable for applications such as point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors, as well as in broadband and networking infrastructure.
