Overview
The TPS54160DGQ is a 60-V, 1.5-A step-down DC/DC converter produced by Texas Instruments. This device features an integrated high-side n-channel MOSFET and operates in a current mode control, which simplifies external compensation and allows for flexible component selection. The TPS54160DGQ is designed to provide high efficiency, especially at light loads, through its pulse skipping Eco-mode. It supports a wide input voltage range of 3.5 V to 60 V and can output voltages from 0.8 V to 58 V. The device is packaged in a 10-pin HVSSOP (DGQ) package with a PowerPAD for enhanced thermal performance.
