What qualifies this part for automotive power rails
For an OEM auditor reviewing PPAP documentation, the AEC-Q100 listing is the evidence they need; a part sold as 'automotive-capable' without it will not pass review. The 125°C ceiling is the hard stop for derating calculations — expect the output current to be limited above 105°C ambient if the board has restricted airflow.
Input range and output flexibility for battery-connected systems
The input voltage range from 3V to 17V accommodates automotive battery transients: cold-crank dips down to 3V and load-dump spikes up to 17V. The 1A continuous output current suits low-power nodes like a 400mA Cortex-M4 supply or a 800mA sensor cluster, but not a 2A infotainment rail — for that, the LMR33630APCQRNXRQ1 (3A) is a closer fit.
Switching frequency and synchronous rectification
The 2.25MHz switching frequency keeps the inductor small (typically 2.2 µH to 4.7 µH) and pushes the fundamental switching noise above the AM band, easing EMI filtering.
Package, footprint, and production status
The part is supplied in an 8-WFDFN exposed pad package (8-WSON 2x2 mm). The base product number TPS62160 covers multiple output-current and package variants; if a 1A part is overkill, the TPS62150 (0.5A) shares the same pinout and package.
