应用须知

  • How to Generate a Regulated VGL Supply Using the TPS65642A
    PDF, 173 Kb, 档案已发布: Dec 8, 2016
    LCD panels require a single or bipolar supply for the source driver and two supply voltages for the gate driver. The TPS65642A device integrates two boost converters to supply the source driver and the positive supply voltage for the gate driver. The negative supply voltage for the gate driver is not integrated but is easily generated with an external negative charge pump which requires only a few
  • Understanding Undervoltage Lockout in Power Devices (Rev. A)
    PDF, 90 Kb, 修订版: A, 档案已发布: Sep 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, 档案已发布: Sep 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, 修订版: C, 档案已发布: Jan 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.
