LD1512
12 Channel Output LED Driver with 8/12/16 bit PWM Controller
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.
FEATURES
• 12 constant output channels
• 8/12/16bit grayscale PWM control
• Output current : set-up at 5mA to 60mA
with three external resistors
• Maximum sinking output voltage : 40V
• CMOS compatible input
• Package : SOP28, SSOP28, 28QFN
• Maximum serial input frequency : 20MHz
• Built in internal RC oscillator : 10MHz
