Passive Filters Fill the Bill At Audio Frequencies:  02/01/01 EDN-Design Ideas / PDF contains multiple circuits - scroll to find this circuit.
Single FET Controls LED Arrray:  04/12/01 EDN-Design Ideas /  PDF contains multiple circuits - scroll to find the one of interest / White-LED backlights are gaining acceptance because they offer higher reliability and simpler drive circuitry than backlights based on CCFL (cold-cathode-fluorescent-lamp) and EL (electroluminescent) technology. This circuit shows a switch-mode boost design that regulates current instead of voltage and switching off individual LEDs or groups of LEDs is not a problem
