ABSOLUTE MAXIMUM RATINGS Parameter Rating Unit VIN, LEDx, RSET 6 V EN/DIM Voltage 6 V Storage Temperature Range −65 to +160 °C Junction Temperature Range −40 to +125 °C Lead Temperature 300 °C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Table 2. ELECTRICAL OPERATING CHARACTERISTICS (Min and Max values are over recommended operating conditions unless specified otherwise. Typical values are at VIN = 4.0 V, EN/DIM = High, and TAMB = 25°C.)
