Overview
The TPS54060DGQR is a 60-V, 0.5-A step-down (buck) regulator with an integrated high-side n-channel MOSFET, designed by Texas Instruments. This device is part of the TPS54060 series and is available in a 10-pin HVSSOP (DGQ) package with PowerPAD™ and a 10-pin 3-mm × 3-mm VSON package. It features current-mode control, which simplifies external compensation and component selection. The regulator is optimized for high efficiency at light loads and includes an Eco-Mode™ that reduces the no-load regulated output supply current to 116 µA. The device also supports adjustable slow start and sequencing, making it versatile for various applications.
