The TPS54540-Q1 from Texas Instruments is a 42-V, 5-A step-down DC-DC converter designed for automotive applications. It features an integrated high-side MOSFET and supports load-dump pulses up to 65 V. The device utilizes current mode control for simple external compensation and flexible component selection.
Key features include high efficiency at light loads with pulse-skipping Eco-mode™, a low operating quiescent current of 146 μA, and a shutdown current of 2 μA. The switching frequency is adjustable from 100 kHz to 2.5 MHz, allowing optimization for efficiency or component size. It also synchronizes to an external clock.
The TPS54540-Q1 includes protection features such as frequency foldback and thermal shutdown to safeguard internal and external components during overload conditions. It is available in an 8-pin thermally enhanced HSOP PowerPAD™ package, suitable for surface mounting.
This device is AEC-Q100 qualified with Device Temperature Grade 1 (-40°C to 125°C ambient operating temperature range) and specific HBM and CDM ESD classifications. It is supported by WEBENCH® Software Tool.
