Abstract

See full text

A LED driver circuit uses a first current source circuit to set an output current, controlled by pulse width modulation and a second current source circuit for charging a storage capacitor. A compensating arrangement is used for increasing the current delivered by the second current source circuit during off period times of the pulse width modulation. This compensates the current drawn from the input and enables better timing control of the input current pulses.
