Overview
The TPS54160ADGQR is a 60-V, 1.5-A step-down (buck) regulator produced by Texas Instruments. This device features an integrated high-side n-channel MOSFET and operates using current mode control, which simplifies external compensation and allows for flexible component selection. The regulator is designed to provide high efficiency, especially at light loads, through its pulse skipping Eco-mode™. It also includes various protection mechanisms such as frequency foldback, thermal shutdown, and under-voltage lockout (UVLO) to ensure reliable operation under different conditions.
