  Constant Current Constant Voltage Buck Converter w/LM25085 (Rev. A)
  PDF, 377 Кб, Версия: A, Файл опубликован: 23 апр 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 Мб, Файл опубликован: 28 апр 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.
