Texas Instruments TPS6290x/TPS6290x-Q1 High-Efficiency and Low IQ 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 VOUT 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).
The Texas Instruments TPS6290x/TPS6290x-Q1 can automatically enter power save mode (if auto PFM/PWM is selected) at light loads to maintain high efficiency. Additionally, to provide high efficiency at very small loads, the device has a low typical quiescent current of 4µA. AEE (Automatic Efficiency Enhancement), if enabled, provides high efficiency across VIN, VOUT, and load current. The device includes a MODE/Smart-CONF input to set the internal/external divider, switching frequency, output voltage discharge, and automatic power save mode or forced PWM operation.
The devices are available in a small 9-pin VQFN package measuring 1.50mm × 2.00mm with 0.5mm pitch. The TPS62903-Q1 devices are AEC-Q100 qualified for automotive applications.
