New High Brightness LED applications such as Displays, Information panels, Signs, Traffic signals, Automotive lighting and Advertising are becoming more and more popular. For such applications new HB LED drivers with constant current outputs were designed. The constant LED current guarantees the same brightness for all LEDs and gives a cost advantages in lighting system solutions, because no external resistors for each individual LED are needed. In this application note it is described an easy design solution to drive an array of High Brightness LEDs, using the STP16CP596 and STP16CL596 LED drivers.
