Overview
The TPS54560BDDAR is a highly efficient 60-V, 5-A step-down DC-DC converter produced by Texas Instruments. This regulator integrates a high-side MOSFET, providing current-mode control for simple external compensation and flexible component selection. It is designed to offer high efficiency at light loads, thanks to its pulse-skipping Eco-mode™, and features a low-ripple pulse-skip mode that reduces no-load supply current to 146 μA. The device is suitable for a wide range of power supply applications, including industrial control, automotive, medical, and aerospace systems.
