Abstract

See full text

A LED driver IC includes a control module(s) for controlling one or more LED drive parameters and non-volatile memory for storing settings data for that control module(s). The control module(s) is fully integrated into the LED driver IC and does not require any control input from off-chip components or signals. Therefore, the space requirements for LED circuits that make use of the LED driver IC can be minimized. Also, the non-volatile memory storage of settings data eliminates the need for an initialization or configuration input each time the LED driver IC is powered on. The non-volatile memory can be a one-time programmable memory or can be a reprogrammable memory.
