Application Notes

  • Generation of a VCOM buffer input using PWM signal
    PDF, 439 Kb, File published: Dec 21, 2015
    In an LCD the backlight shines through the liquid crystal material and the voltage across the liquid crystal controls how much light shines through it. An active matrix LCD (AMLCD) contains many pixels arranged in a grid pattern. The voltage across each pixel is controlled individually so that high resolution images can be created. One terminal of every pixel is connected to a common plane. The v
  • Understanding Undervoltage Lockout in Power Devices (Rev. A)
    PDF, 90 Kb, Revision: A, File published: 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.
