CAV4109 General Description

The CAT4109/CAV4109 is a 3

*channel constant

*current LED driver, requiring no inductor. LED channel currents up to 175 mA are programmed independently via separate external resistors. Low output voltage operation of 0.4 V at 175 mA allows for more power efficient designs across wider .
