DM621 - SiTi

DM621 12-CHANNELS PRE-PROGRAMMABLE CONSTANT CURRENT LED DRIVER

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