The TPS54312QPWPRQ1 from Texas Instruments is a member of the SWIFT family of DC/DC regulators. This synchronous buck converter operates with an input voltage range of 3V to 6V and can deliver up to 3A of continuous output current. It is designed for high-density systems requiring efficient power conversion.
Key electrical specifications include a fixed 1.2V output voltage with 1% initial accuracy, and selectable fixed PWM frequencies of 350kHz or 550kHz. The device features integrated 60mΩ MOSFET switches for high efficiency. It also includes an undervoltage-lockout circuit set at 3V, internal compensation for low parts count, and protection features like peak current limit and thermal shutdown.
This converter is housed in a thermally enhanced 20-pin TSSOP PowerPAD package, measuring 6.3mm x 6.4mm, which helps reduce board area by eliminating the need for bulky heatsinks. The TPS54312QPWPRQ1 is qualified for automotive applications and is suitable for point-of-load regulation in high-performance digital systems and communication infrastructure.
Applications include low-voltage, high-density systems with power distributed at 5V or 3.3V, point-of-load regulation for DSPs, FPGAs, ASICs, and microprocessors, broadband, networking, and optical communications infrastructure, and automotive telematics.
