DESCRIPTION
The LD1512 is specifically designed for LED lighting or display applications. The 12-channel constant output current is controlled by 3 external resistors (IOUT = 5mA to 60mA). The device consists of 16 x 12 bit shift register, latches, built-in OSC, 12 constant current drivers and 8/12/16 bit PWM controller.
The main applications are decorative LED lighting, indoor/outdoor LED video or message display systems.
