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, 档案已发布: Apr 22, 2011
