DD313 Datasheet (SiTi) - 3-Channel High Constant Current LED Driver

DD313, 3-Channel High Constant Current LED Driver

DD313 is a high constant current driver designed for power LED applications.

It incorporates three-channel constant current circuitry with c urrent value set by three external resistors.

The three enable pins are specifically designed for independent control over each of the three output terminals.
