6. Application Information

The TPS84250 operates over a wide input voltage range of 7V to 50V and produces an output voltage of 2.5V to 15V. Because device performance varies over such a wide operating range, there are some important considerations when operating close to boundary constraints. When designing with the TPS84250, the user must choose three main parameters.

    1. The output voltage

    2. UVLO threshold

    3. switch level
