General Description

DM412 is a PWM enabled LED driver specifically designed for LED video display or lighting applications.

Each channel has linear adjustable 16-bits (65536 steps) grayscale PWM control current outputs.

It incorporates shift registers, data latches, 3-channel constant current circuitry with current value set by 3 external resistors, and built-in oscillator for PWM functioning.

Key Features
