Constant current drivers have one specified output current labeled in amps and a range of voltages that will vary depending on the wattage rating of the LED. This type of driver is designed for LED lights that require a fixed output current and a ranged output voltages. Motor Drivers ICs. Protection and Control. Display Power and Control. Why Drive White LEDs with Constant Current? (color) are tested and best controlled by driving it with constant current. A typical white LED specification can be seen in Figure 3. For a typical white LED, the entire electrical specification is. Assumption: A single LED is being driven, based on 'flashing the LED about 3 times.' The constant current driver is going into overload, due to being forced to dissipate power far over its design limits. From the datasheet of the LED, it has a forward voltage of 3.2 Volts. The LED driver has a minimum DC output voltage of 17 Volts.
