The DCS-Control architecture combines hysteretic and voltage-mode control, giving fast transient response without external compensation components — the loop is stable with ceramic output capacitors.","metaTitle":"TPS62171QDSGTQ1 – Automotive Buck Regulator 500 mA 2.25 MHz","metaDescription":"Texas Instruments TPS62171QDSGTQ1, AEC-Q100, 3–17 V input, 1.8 V fixed output, 500 mA synchronous buck in 8-WSON.
