Overview
The TPS54360DDAR from Texas Instruments is a high-performance, 60-V input, 3.5-A step-down DC/DC converter. This device is integrated with a high-side MOSFET and is designed to operate efficiently across a wide input voltage range of 4.5 V to 60 V, with an absolute maximum of 65 V. It is particularly suited for applications requiring high reliability and efficiency, such as industrial, automotive, and communications power systems. The TPS54360DDAR features Texas Instruments' Eco-mode™, which enhances efficiency at light loads through pulse skipping, reducing the no-load supply current to 146 µA and shutdown current to 2 µA when the enable pin is pulled low.
