The TPS62901 is a highly-efficient, small, and flexible synchronous step-down DC-DC converter that is easy to use. A selectable switching frequency of 2.5MHz or 1.0MHz allows the use of small inductors and provides fast transient response. The device supports 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.

The TPS62901 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, if enabled, provides high efficiency across VIN, VOUT, and load current. The device includes a MODE/S-CONF input to set the internal and external divider, switching frequency, output voltage discharge, and automatic power save mode or forced PWM operation.

The device is available in small 9-pin VQFN package measuring 1.50mm × 2.00mm with 0.5mm pitch.
