It's part of the Automotive, AEC-Q100 series, so it's qualified for the temperature and reliability demands of under-hood and chassis-mounted electronics — engine control units, transmission modules, sensor power rails, and infotainment supplies that see a 4V to 38V input bus. The synchronous rectifier means the low-side switch is integrated, which saves an external Schottky diode and improves efficiency at the 5V output level — a real consideration when the board is in a sealed enclosure with limited airflow. The 4V minimum input lets it run off a 5V rail with headroom, or a single-cell Li-ion pack in a step-down pre-regulator stage. The 38V maximum covers 12V and 24V automotive systems with margin for load-dump transients, so you don't need an external clamp for most passenger-vehicle buses. Fixed 5V output removes the need for an external feedback divider — one fewer resistor pair to place and tolerance-stack. The 250 kHz to 2 MHz switching range lets you trade off inductor size against efficiency: lower frequency for better efficiency in a tight thermal budget, higher frequency for a smaller inductor when board area is the constraint. The junction temperature rating of -40°C to 150°C (TJ) is the full automotive range. Surface-mount only.","metaTitle":"STMicroelectronics A6986F5V Automotive Buck Regulator","metaDescription":"A6986F5V from STMicroelectronics is an AEC-Q100 qualified step-down regulator. 4V to 38V input, 5V fixed output at 1.5A.
