Overview
The TPS54360DDA from Texas Instruments is a 60-V, 3.5-A step-down regulator with an integrated high-side MOSFET. This device is designed to survive load dump pulses up to 65 V per ISO 7637, making it suitable for various high-voltage applications. It features current mode control, which simplifies external compensation and allows for flexible component selection. The regulator includes a low ripple pulse skip mode that reduces the no-load supply current to 146 µA, and a shutdown supply current of 2 µA when the enable pin is pulled low. The TPS54360DDA is available in an 8-terminal thermally enhanced HSOIC PowerPAD™ package and operates over a junction temperature range of –40°C to 150°C.
