Patent abstract

Describe is a device for a multiplexing, output current-sensed, boost converter circuit which may be used as an LED driver. A boost converter LED driver circuit using a single set of passive external LC components for controlling the current through, and thus the output of, one and more than one bank of LEDs. The present invention allows for regulated current in one and more than one bank of LEDs by sensing current in the controller. The output voltage of a switcher adjusts it's level automatically until the current to the LEDs is set to the desired LED threshold requirement.
