Application Notes
- Constant Current Constant Voltage Buck Converter w/LM25085 (Rev. A)PDF, 377 Kb, Revision: A, File published: 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. - Designing Non-Invert Buck-Boost (Zeta) Cnvrts w/a Buck P-FET CntrlPDF, 299 Kb, File published: Apr 22, 2011
- Transient Response versus Ripple – An Analysis of Ripple Injection TechniquesPDF, 2.9 Mb, File published: 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. - Reduce buck-converter EMI and voltage stress by minimizing inductive parasiticsPDF, 926 Kb, File published: Jul 21, 2016
