The TPS6281x device is a high-frequency, synchronous, step-down converter optimized for a small solution size and high efficiency. The devices focus on high-efficiency, step-down conversion over a wide output current range. At medium to heavy loads, the converter operates in PWM mode and automatically enters Power Save Mode operation at light load to maintain high efficiency over the entire load-current range. The internal compensation circuit allows a compact solution and small external components. The device is available in a 3.0-mm × 2.0-mm, 9-pin VQFN package.
