TPS6290x/TPS6290x-Q1 Buck Converters

Texas Instruments TPS6290x/TPS6290x-Q1 High-Efficiency and Low I_Q Buck Converters are highly efficient, small, and flexible synchronous step-down DC-DC converters that are easy to use. A selectable switching frequency of 2.5MHz or 1.0MHz allows the use of small inductors and provides a fast transient response. The devices support a high V_OUT accuracy of ±1% with the DCS-Control topology. The wide input voltage range of 3V to 17V supports a variety of nominal inputs like 12V supply rails, single-cell or multi-cell Li-Ion, and 5V or 3.3V rails. These devices have a continuous output current of up to 1A (TPS62901), 2A (TPS62902), or 3A (TPS62903/TPS62903-Q1).
