  • Automated Frequency Response Analyzer
    PDF, 939 Kb, Datei veröffentlicht: Oct 9, 2013
    This application report discusses a new method of doing stability Analysis testing by using basic labequipment, while not requiring any specific instruments.
  • Constant Current Constant Voltage Buck Converter w/LM25085 (Rev. A)
    PDF, 377 Kb, Revision: A, Datei veröffentlicht: Apr 23, 2013
    In many applications, a constant-current constant-voltage (CC/CV) dc source is needed. The I-Vcharacteristic of a constant-current constant-voltage (CC/CV) source is shown in Figure 1. This applicationreport presents an external op-amp based accurate current limit circuit suitable for CC/CV operation whenthe required constant current range is very narrow.
  • Transient Response versus Ripple – An Analysis of Ripple Injection Techniques
    PDF, 2.9 Mb, Datei veröffentlicht: Apr 28, 2014
    In this application note the implications of ripple injection techniques, aimed at minimizingoutput ripple voltage, on the transient response of a supply are highlighted. The results help choose a suitable ripple injection technique after striking a balance between the output ripple voltage and the transient response required by the load.
