Abstract:
An LED driver includes an embedded non-volatile memory (NVM) capable of being programmed and storing control data for setting a variety of features of the LED driver, such as the maximum current for driving the LEDs, analog parameters such as the resistance of the internal resistor for setting the reference current for the LEDs, and the operation modes of the charge pump of the LED driver. This enables implementation of multiple LED driver product options without the need for different metallization steps during the fabrication process for the LED driver.
