LED Drive Methods and Circuit. Design. LEDs are current-driven light-emitting devices, the characteristic values of which are specified using forward current . circuit. ? Works even for low currents. (Low currents are better than high voltages for driving transistors.) ? Requires a high voltage. Parallel circuit. ? Voltage can be
using NCL30051. The step-by-step design procedure for the. NCL30051-based LED power supply is provided in this section. In case the LED driver (Type 1 circuit) is being designed, the same design procedure and principles apply, albeit with an added complexity related to the CCCV circuit and variations in the voltage,

The portable electronic products are widely used in daily life. Because most of these products need screen or backlight, the white LED is popularly applied to these products. In many applications, we need an IC driver to supply the necessary power to drive the White LEDs. There are two kinds of drivers, parallel type and
of LED luminaires, to explain the requirements for an LED driver and to help find an appropriate "LED drivers". As a leading manufacturer of switching power supplies FRIWO has taken on the challenge to engineer and manufacture LED drivers which solve the aforementioned Structure of an LED and circuit symbol.
