    Abstract: A sequential linear light emitting diode (LED) driver utilizing a headroom control technique is disclosed. A headroom control circuit with a micro-tapped segment of LEDs causes one or more of said LEDs to emit light before the direct current voltage is sufficiently high to cause the main LED string(s) to emit light.
