Introduction
New high brightness LED (HB LED) applications such as displays, information panels, signs, traffic signals, automotive lighting and advertising are becoming more and more popular. For these applications new HB LED drivers with constant current outputs have been designed. The constant LED current guarantees the same brightness for all LEDs and provides a cost advantage in lighting system solutions, as there is no need for external resistors for each individual LED. This document describes a simple design solution to drive an array of high brightness LEDs, using the STP16CP05 and the STP16CPS05 LED drivers.
