  Off-Line SMPS Failure Modes PWM Switchers and DC-DC Converters
  PDF, 71 Кб, Файл опубликован: 22 мар 2000
  Today's voltage regulator modules (VRMs) employ off-line SMPS techniques. Traditionally, they are usually discarded when they fail because they are so challenging to debug and so inexpensive to replace. Investigation of these failed modules reveals some common failure modes. Some failures are caused by other systems' passive components that fail after repeated electrical stress. Recognizing these

  Understanding Buck Power Stages In Switchmode Power Supplies
  PDF, 173 Кб, Файл опубликован: 4 мар 1999
  A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the buck power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous
