Anwendungshinweise

  • Using The TPS6235x Without The I2C Interface
    PDF, 69 Kb, Datei veröffentlicht: May 17, 2007
    The TPS6235x series of DC/DC converters have an I2C-compatible interface that facilitates changing the output voltage for dynamic voltage-scaling applications. However, it is possible to use the TPS6235x series of converters, without the I2C interface, as a standalone DC/DC converter that can be dynamically switched between two fixed voltages. This technique does not work for the TPS62351.

    When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
