LD1510

3Channel Output LED Driver with 12 bit PWM Controller

The LD1510 is specifically designed for LED lighting or display applications. The 3-channel constant

output current is controlled by 3 external resistors (IOUT = 5mA to 100mA). The device consists of 3 x 12

bit shift register, latches, built-in OSC, 3 constant current drivers and 8/12 bit PWM controller.

The main applications are decorative LED lighting, indoor/outdoor LED video or message display systems.

FEATURES

• Output current : set-up at 5mA to 100mA

• 8/12bit grayscale PWM control with three external resistors

• Maximum sinking output voltage : 17V

• 5.0V CMOS compatible input

• Package : SOP16, SSOP16

• Maximum serial input frequency : 10MHz

• Built in internal RC oscillator
