CAT4008 Description

The CAT4008 is an 8 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4V (for 2 to 100mA LED current) allows for more power efficient designs.
