General Description

The DM621 is an innovative LED driver that integrates a new data transmit interface to acplish 2-wires control for lighting applications.

By the bination of SIN and DCK, DM621 could be pre-programmed to set the operating modes that involve GCK frequency division, PWM grayscale selection, inverse IOUT PWM signal, and GCK frequency selection.

DM621 also provides the auto-latch function and incorporates a particular PWM method (AS-PWM).
