TPS43061RTER – TEXAS INSTRUMENTS

The TPS43061RTER is a 600mA, synchronous step-down converter from Texas Instruments, housed in a thermally enhanced 16-pin QFN package (4x4mm). It employs a hysteretic control architecture, enabling fast transient response and minimizing output voltage ripple, particularly beneficial in applications requiring low noise. Operating from an input voltage range of 2.7V to 5.5V, it efficiently regulates output voltages between 0.8V and V_IN. The device features an adjustable output voltage via an external resistor divider and integrates a soft-start function to limit inrush current. Its internal compensation simplifies design, while its high efficiency (up to 96%) minimizes power loss._x000D_
