  • LED CONTROLLER ASIC AND PWM MODULE THEREOF
    Publication number: 20120146535
    Abstract: An LED controller application specific integrated circuit includes a host interface and a PWM module. The PWM module is configured to control a plurality of LED devices, and comprises a PWM data buffer, an arithmetic core and a plurality of PWM channels. The PWM data buffer is configured to store PWM turning-point data from the host. The arithmetic core is configured to generate PWM data according to the PWM turning-point data stored in the PWM data buffer. The plurality of PWM channels are configured to receive the PWM data, and each comprises a PWM controller and a PWM I/O interface. The PWM controller is configured to control the operation of the PWM channel. The PWM I/O interface is configured to connect to an LED device.
