Texas Instruments TPS54360 and TPS54360-Q1 are 60V, 3.5A Step-Down DC-DC Converters with an integrated high side MOSFET. They are able to survive load dump pulses up to 65V per ISO 7637. These TI DC-DC converters features current mode control that provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146µA. Shutdown supply current is reduced to 2µA when the enable pin is pulled low. Undervoltage lockout is internally set at 4.3V but can be increased using the enable pin. The output voltage start up ramp is internally controlled to provide a controlled start up and eliminate overshoot. TI TPS54360/TPS54360-Q1 have a wide switching frequency range that allows either efficiency or external component size to be optimized. Frequency foldback and thermal shutdown protect internal and external components during overload conditions. These TI devices are designed for use in 12V, 24V, and 48 V industrial, automotive, and communications power systems. Additionally, the TPS54360-Q1 series is AEC Q100 Certified for use in the Automotive Industry.
