  • Examples Of Applications With The Pulse Width Modulator TL5001
    PDF, 462 Kb, Archivo publicado: enero 1, 1997
    Switched-mode techniques are used more and more nowadays for the design of power supplies. Switch mode power supplies have considerably higher efficiency when compared to designs employing linear regulators, and can be used for higher output powers. The rectified input voltage in a switching regulator is chopped by means of a switch. The LC network after the switch smoothes this voltage, resulting
  • Designing with the TL5001 PWM Controller (Rev. A)

    Electrical and electronic products required to be lighter, smaller, use less power, and cost less. Manufacturers are turning to small high-frequency dc-to-dc converters for the power supply solution. The TL5001, pulse-width modulator (PWM) control integrated circuit, when combined with a few external components, can implement the converters and operate at frequencies to 400 kHz. This document p

  • Off-Line SMPS Failure Modes PWM Switchers and DC-DC Converters
    PDF, 71 Kb, Archivo publicado: marzo 22, 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 Kb, Archivo publicado: marzo 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. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous

  • Basic Calculation of a Boost Converter's Power Stage (Rev. C)
    PDF, 186 Kb, Revisión: C, Archivo publicado: enero 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.
