Notas de aplicación

  • TPS61020 Boost Converter Start-Up and Precharge
    PDF, 488 Kb, Archivo publicado: enero 28, 2010
    The TPS61020 is a highly integrated, low-power, boost converter ideally suited for portable battery-powered equipment. To improve start-up performance from a power-limited source such as a battery, the TPS6102x family uses different steps and modes to reduce demand on the battery. This prevents the battery bus from sagging during start-up and improves start-up operation at low voltage.

  • TPS6102x Boost Converter Down Conversion Mode
    PDF, 159 Kb, Archivo publicado: dic 16, 2004
    The TPS61020 is a highly integrated, low-power, boost converter ideally suited for portable battery-powered equipment. The integrated down conversion mode allows the boost converter to operate with the input voltage greater than the output voltage, which is normally only possible with more complicated converters.

    This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed.

    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.
