Buck constant current
WebThis buck converter can also be used as a high-power LED driver module. The module comes with two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in. When used as a lithium battery charger, you can set the float voltage and charge current to show it is charging or already full.

WebConstant Current Buck Controller for High Switching Frequency LED Driver FL7760 The FL7760 is a constant current step−down CCM controller for wide output power LED lighting applications. The FL7760 adapts hysteretic reference architecture that accurately regulates LED current by sensing voltage across an external high side sense resistor. This WebMar 4, 2024 · When you say "output current is 3 A," we're inferring that's the maximum average load current Iavg. The peak inductor current is higher than Iavg by Iripple/2. So your inductor needs a rated DC current of at least 3A. If the peak current limit for the controller is 6A, then it's wise to use an inductor with a saturation current of at least 6A.

WebIn the equations (1) and (2), the output current is used as the . This is the average current of the inductor. As shown in the lower part of Figure 2, greater losses are generated in the actual ramp waveforms. If the current waveform is sharper (peak current is higher), the effective current is obtained by integrating the square of the differential
