Abstract
In one embodiment, a method of forming an LED control circuit may include configuring the LED control circuit to receive a sense signal that is representative of a value of an LED current flow through a plurality of LED strings wherein each LED string includes a plurality of series coupled LEDs; configuring a detector circuit of the LED control circuit to detect the LED current being no greater than a first value and responsively initiate forming a first time period; and configuring the LED control circuit to inhibit forming the LED current responsively to termination of the first time period.
