Light emitting diode driver for load and supply changes

Light emitting diode driver for load and supply changes

In one example, a system includes a load module, a power module, a series module, and a control module. The power module is configured to generate a supply power. The load module is configured to select a subset of light emitting diodes (LEDs) from a set of LEDs. The series module is configured to r...

description In one example, a system includes a load module, a power module, a series module, and a control module. The power module is configured to generate a supply power. The load module is configured to select a subset of light emitting diodes (LEDs) from a set of LEDs. The series module is configured to receive the supply power from the power module, dissipate a portion of the supply power, and output, to the subset of LEDs, a remaining portion of the supply power as a load power. The control module is configured to drive the series module to limit an amount of power at the subset of LEDs.
