TPS54060ADRCR – TEXAS INSTRUMENTS

The TPS54060ADRCR is a 600mA, synchronous step-down converter from Texas Instruments, packaged in a space-saving 10-pin, 3x3mm QFN package. It operates from a wide input voltage range of 2.7V to 5.5V, making it suitable for applications powered by single-cell Li-ion batteries or 5V USB supplies. This device features a fixed 1.8V output voltage, ideal for powering low-voltage microcontrollers and other digital logic. The TPS54060ADRCR employs a constant-frequency current mode control architecture, enabling fast transient response and excellent line and load regulation. Its internal compensation simplifies design, requiring minimal external components. Efficiency is maximized through the use of synchronous rectification, typically exceeding 90% at moderate loads. Key features include a low quiescent current (Iq < 100µA) for extended battery life in portable applications, soft-start functionality to minimize inrush current, and overcurrent and thermal shutdown protection for robust operation. Its small size and high efficiency make the TPS54060ADRCR particularly well-suited for portable devices, wearables, and space-constrained designs requiring a regulated 1.8V supply from a readily available input voltage.
