Notas de aplicación

  • Understanding Undervoltage Lockout in Power Devices (Rev. A)
    PDF, 90 Kb, Revisión: A, Archivo publicado: sept 19, 2018
    Many integrated circuits include an undervoltage lockout (UVLO) function to disable the device at low supply voltages. Below the minimum supply voltage the function and performance of a device may be undefined making it impossible to predict system behavior. This application note explains how to correctly understand the undervoltage lockout specification in the data sheets of TI's power products.
  • Minimizing Ringing at the Switch Node of a Boost Converter
    PDF, 201 Kb, Archivo publicado: sept 15, 2006
    The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter.
  • Basic Calculation of a Boost Converter's Power Stage (Rev. C)
    PDF, 186 Kb, Revisión: C, Archivo publicado: enero 8, 2014
    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.
