The TPS54531DDAR from Texas Instruments is a 28V, 5A non-synchronous buck converter designed for efficient power regulation. It features an integrated 80 mΩ high side MOSFET and supports continuous output currents up to 5A. The device operates with an input voltage range of 3.5V to 28V and provides an adjustable output voltage down to 0.8V.
To enhance efficiency at light loads, the TPS54531DDAR incorporates a pulse skipping Eco-mode™ feature. It also boasts a typical shutdown quiescent current of 1 μA, making it suitable for battery-powered applications. The converter operates at a fixed switching frequency of 570kHz, simplifying compensation calculations and allowing the use of ceramic output capacitors.
Protection features include cycle-by-cycle current limit, frequency fold back, and thermal shutdown, safeguarding the device and load during overload conditions. The TPS54531DDAR is available in an easy-to-use, thermally enhanced 8-pin SOIC PowerPAD™ package, optimized for improved thermal performance. It is suitable for various applications including consumer electronics, industrial power supplies, and distributed power systems.
Mounting is achieved via surface mount technology. The operating temperature range is -40°C to 85°C (TA).
