What are the two resistors doing in this circuit, and how do I calculate their value?
- Am I right in thinking that while I can have an arbitrarily long chain of leds by supplying sufficient voltage, the maximum current through those leds (and therefore the ccr driver) can be 160mA
What is figure 11 illustrating then with the use of a resistor on one ccr?
If I need still more current than this, is there a better product or technique I could use?
I'm trying to understand the circuit in figure 12, on page 6 of this data sheet - http://www.onsemi.com/pub_link/Collateral/NSI45090JD-D.PDF'Dimming using PWM'I want to use this constant current led driver with a ws2801 pwm driver (also cc) to allow me to control higher power leds with the ws2801, while retaining constant current functionality. I'm loaded with questions -
Would be really nice to modify the schematic above to use common anode still...
