Input range spans 3V to 17V, covering common 5V, 12V, and 15V buses without external level shifting. For a new design-in or a BOM fill, this is a current, supported part with no imminent supply disruption. ## Thermal and layout notes for the 3x3 QFN The datasheet recommends a 4-layer PCB with at least 4 vias in the thermal land. ## Single-output, positive-configuration regulator This is a single-output, positive-configuration regulator. The fixed 1.8V output means no external resistor divider is needed for the feedback — just the output capacitor and inductor. The DCS-Control™ architecture provides fast transient response and a seamless transition between PWM and power-save modes at light loads, which matters for battery-powered or low-standby designs.","metaTitle":"TPS62131RGTT TI DCS-Control Buck Regulator 1.8V 3A","metaDescription":"TPS62131RGTT from Texas Instruments: step-down buck regulator, fixed 1.8V output, 3A, 2.5MHz switching, 16-VQFN (3x3).

The TPS62130 is an adjustable output version (typically 0.9V to VIN). They share the same pinout, package, and 3A current rating, so a board designed for the TPS62130 can accept the TPS62131RGTT if a 1.8V rail is acceptable."},{"question":"Can TPS62131RGTT be used with a 5V input?","answer":"Yes. The input range is 3V to 17V, so 5V is well within the operating window.
