They are configured as either inductorless (charge pump) or switching regulator-based LED drivers that support driving white LEDs in series, parallel or combination. A constant current LED driver is an LED power supply that regulates the current flowing through an LED array so as to maintain a desired level of light output. When driving multiple LEDs in a single string, efficiencies greater than 95% may be attained together with very accurate LED current matching. This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED. Constant voltage LED drivers maintain a constant voltage. DC 800ma Constant Current LED Drive Driver Power Supply 12V Car battery 10W C50.
