It's the variant you pick when the load needs exactly 1.8V — no resistor divider, no feedback network to trim. Rated for 1A continuous output at 2.25 MHz switching frequency, the part uses synchronous rectification to keep efficiency up and the external inductor small — a 1 µH to 2.2 µH part in the 0805 or 1210 footprint handles the ripple. ## Industrial temperature band and where it fits The 2.25 MHz switching frequency keeps the converter out of the AM broadcast band and lets the output filter use small ceramic caps — a 10 µF MLCC on the output handles the bulk of the decoupling. Input voltage range from 3V to 17V means it runs cleanly from a 5V or 12V supply rail, or from a 3.3V rail with headroom for pre-bias startup. The fixed 1.8V output is common for powering sensor analog front-ends, low-voltage MCU I/O banks, or a dedicated DDR termination rail in mixed-voltage designs. The base product number TPS62161 covers a family of fixed-output-voltage variants (1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and adjustable). If the BOM calls for a different rail, the same pin-compatible footprint handles the sibling — no board spin needed.","metaTitle":"TPS62161DSGR Step-Down Regulator, 1.8V Fixed Output, 1A","metaDescription":"Texas Instruments TPS62161DSGR buck converter with DCS-Control, fixed 1.8V output, 1A, 2.25MHz switching.
