The AN30888A/B Series' wide operating power supply range allows configuration of the power supply and the number of LEDs to drive required by the specific application.

This fixed-voltage output rail then supplied each string via stage 3, comprising a dedicated DC-to-DC converter providing a regulated current. All other trademarks are the property of their respective owners. First, efficacies have dramatically improved (see the TechZone article LED Efficacy Improvement Shows No Signs of Slowing) such that 1-Watt devices can output over 100 lumens.
