  How to Compensate the TPS6510x and the TPS6514x
  PDF, 1.1 Mb, File published: Aug 30, 2016
  The boost converters in the TPS6510x (TPS65100 TPS65101 TPS65105) and the TPS6514x (TPS65140 TPS65141 TPS65145) series use external loop compensation providing high flexibility in LCD supply design. If designing a typical application scheme use the recommended components from the TPS6510x datasheet (SLVS496) and the TPS6514x datasheet (SLVS497). This application note gives a deeper understand

  Basic Calculation of an Inverting Buck-Boost Power Stage (Rev. A)
  PDF, 431 Kb, Revision: A, File published: Aug 28, 2017
  This application note provides basic formulas that you need to design the power stage of an invertingbuck-boost converter. The premise is that the power switch is integrated in the IC and the rectification isdone by a diode (non-synchronous power stage). It provides all the formulas and considerations that youneed to select the external power components such as the inductor the diode and t

  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.

  Basic Calculation of a Boost Converter's Power Stage (Rev. C)
  PDF, 186 Kb, Revision: C, File published: 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.
