The fixed 1.2 V output and integrated synchronous rectifier eliminate the need for an external Schottky diode, simplifying the BOM for point-of-load supplies in automotive ECUs, sensor modules, and CAN transceiver rails. ## Switching frequency and package — layout decisions The 2.25 MHz switching frequency lets you use a small inductor (typically 2.2 µH to 4.7 µH) and small ceramic output capacitors, which keeps the total solution footprint tight for space-constrained automotive PCBs. The -40°C to 115°C operating temperature range covers under-hood and cabin environments.","metaTitle":"TPS62242QDDCRQ1 Buck Converter, 2.25 MHz, 300 mA, AEC-Q100","metaDescription":"Texas Instruments TPS62242QDDCRQ1 step-down buck regulator, 2.25 MHz switching, 300 mA output, AEC-Q100 qualified.
