The TPS62902 is a highly-efficient, small, and flexible synchronous step-down DC-DC converter that is easy to use. A selectable switching frequency of 2.5 MHz or 1.0 MHz allows the use of small inductors and provides fast transient response. The device supports high V OUT accuracy of ± 1% with DCS-Control topology. The wide input voltage range of 3-V to 17-V supports a variety of nominal inputs, like 12-V supply rails, single-cell or multi-cell Li-Ion, and 5-V or 3.3-V rails.

The TPS62902 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 4 µA. AEE, if enabled, provides high efficiency across V IN, V OUT, and load current. The device includes a S-CONF/MODE input to set the internal/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 1.50 mm × 2.00 mm with 0.5-mm pitch.
