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 - Designing Switching Voltage Regulators With the TL494 (Rev. E)PDF, 329 Kb, 修订版: E, 档案已发布: Jul 26, 2005
Designing Switching Voltage Regulators With the TL494 - Understanding Buck Power Stages In Switchmode Power SuppliesPDF, 173 Kb, 档案已发布: Mar 4, 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.
