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. - Reduce buck-converter EMI and voltage stress by minimizing inductive parasiticsPDF, 926 Kb, File published: Jul 21, 2016
