  Short-to-Battery Protection Strategies for Class-D Amplifiers
  PDF, 3.2 Mb, 档案已发布: Nov 11, 2016
  This document introduces the potential faults that can occur in class-D amplifier solutions, and describes how most faults are intrinsically protected for and how to extend coverage to protect against all short-circuit faults. Of particular focus is the case when an output is shorted to a battery voltage higher than the device supply voltage. This fault allows the parasitic body diode found in the

  Filter-Free Class-D Audio Amplifiers
  PDF, 259 Kb, 档案已发布: Nov 9, 2009
  Traditional Class-D amplifiers lose efficiency if they do not use output LC filters. Texas Instruments offers many Class-D amplifiers that are designated Filter-Free. This means they do not require an output LC filter to maintain high efficiency. However, in some cases an LC or ferrite bead filter is required for EMC.
