Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
The need for a constant current source has been illustrated in this project which uses the TPS54232 step down swift DC/DC converter. The need for a constant current source has been illustrated in this ...
This dimming controlled LED driver circuit is designed using LM3409 P-channel MosFET controller for step-down (buck) current regulators.The LM3409 devices use Constant Off-Time (COFT) control to ...
