Abstract
An LED driver design has a single controller used to drive multiple strings of LEDs. In one aspect there is dynamic threshold voltage setting so that the individual characteristics of the LED strings can be taken into account in the voltage control loop. In another aspect, excess energy is dissipated off-chip in a dedicated heat dissipater, and the routing of current to the heat dissipater is controlled dynamically such that a desired integrated circuit biasing remains stable.
