Texas Instruments TPS543xx/-Q1 & TPS545xx/Q1 DC-DC Converters
Texas Instruments TPS543xx/-Q1 and TPS545xx/-Q1 are 42V input 3.5A and 5A step-down DC-DC converters with an integrated high side MOSFET. TI TPS54360 and TPS54560 are 60V input 3.5A and 5A DC-DC converters with integrated high side MOSFET. TPS54341 / TPS54541 and TPS54361 / TPS54561 devices offer 100kHz to 2.5MHz adjustable switching frequency while TPS543x0 and TPS545x0 devices have 100kHz to 2.5MHz fixed switching frequency. These TI step-down converters survive load dump pulses up to 65V per ISO 7637. All of the parts offer high efficiency at light loads with pulse skipping Eco-mode. The TPS543xx-Q1 & TPS545xx-Q1 devices are AEC-Q100 qualified for automotive applications.
