Active production, AEC-Q100 on the label
The TPS62090QRGTRQ1 is a Texas Instruments automotive-grade step-down buck regulator carrying AEC-Q100 qualification and DCS-Control™ architecture.
3 A output, 2.8 MHz — the so-what for your rail
The 3 A continuous output rating covers most automotive sub-system loads: infotainment processors, camera modules, ADAS pre-regulators. The 2.8 MHz switching frequency pushes the fundamental and its harmonics above the AM broadcast band (530–1710 kHz), which simplifies EMI filtering in a vehicle's radio environment. Output voltage adjusts from 0.8 V up to 6 V. The 0.8 V floor lets you feed a 1.0 V or 1.2 V core rail directly; the 6 V ceiling covers 5 V sensor supplies and CAN transceiver rails.
Under-hood temperature grade
That's the full automotive under-hood envelope — cold crank at -40°C and hot-soak after engine-off at 125°C. The 16-VQFN (3x3 mm) package keeps the footprint small enough for space-constrained ECU designs.
