Tutorial - Light-emitting Diodes (LEDs)
about a year ago
The data sheet’s “Application Diagram” circuit does show the battery connected to the device without a current limiting resistor. This sort of implies that the “IC” has current limiting capability as well as voltage boosting. Anyone tried it on 2V to see if it works? It would seem that putting a small enough resistor for the blue led would likely overload the red led. If the IC has no current regulation capability.

How does one power these? Constant current, current limiting resistor, or constant voltage? The spec sheet does not specify. Maybe I need to experiment and destroy a few…
No public wish lists :(
