  • Designing Switch-Mode Power Supplies with the TL598 Application Report (Rev. B)
    PDF, 1.0 Mb, Revisión: B, Archivo publicado: jul 1, 1992
    Designers of switching power supplies commonly specify MOSFET switches and therefore need control circuits with outpus capable of directly driving MOSFET switches. The TL598 control circuit was designed with this capability to avoid any need for additional output circuitry. After functionally describing the TL598, this report directs the designer through a complete dc-to-dc converter design using

    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
