Nettet12. jun. 2024 · As you noticed, when connected to the driver chip, you measure only the LED's forward voltage between the source and the driver pin. What the driver does is, it puts the voltage level of the sink pin high enough so only the specified current will flow through the LED - by regulating its forward voltage. Usually it works the opposite way … Nettet2. If your output is either sourcing current or sinking it, it means the device is actively trying to drive the voltage on that output to one of the supply rails; the positive supply …
