CAT4104
ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
* Keeping LEDx pin voltage below 6 V in operation is recommended to minimize thermal dissipation in the package.
Typical application circuit with external components is shown on page 1.
ELECTRICAL OPERATING CHARACTERISTICS
Min and Max values are over the recommended operating conditions unless specified otherwise.
Typical values are at VIN = 5.0 V, T
Note 1: Min and Max values are tested for I
