M66503ASP Description
The M66503A is a constant current LED driver IC, whose output current is variable. The IC’s functions include 16-bit serial input/parallel output shift register with output latch. The product uses Bi-CMOS process for highly accurate constant current driving, permitting high-efficiency LED driving without using a resistor that limits LED current.
