The TPSM82902 is a highly efficient, small, and flexible synchronous step-down DC-DC converter MicroSiP package module that is easy to use. A selectable switching frequency of 2.5 MHz or 1.0 MHz allows the use of small components and provides fast transient response. The device supports high V_OUT accuracy of ± 1% with the 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 TPSM82902 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 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 device is available in small 11-pin MicroSiP package measuring 3.0 mm × 2.8 mm × 1.6 mm with an integrated 1-µH inductor.
