The TPS62992-Q1 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 ± 1.5% across the entire operasting temperature range and enhanced load transient performance with the DCS-Control topology. The wide 3-V to 10-V input voltage range supports a variety of nominal inputs, like 9-V supply rails, single-cell or multi-cell Li-Ion, and 5-V or 3.3-V rails.

The TPS62992-Q1 can automatically enter power save mode (if auto PFM or 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 MODE/Smart-CONF input to set the internal and external divider, switching frequency, output voltage discharge, and automatic power save mode or forced PWM operation.
