Ordering number : ENA2104 LV5980MC Bi-CMOS IC Low power consumption LV5980MC Specifications Absolute Maximum Ratings at Ta = 25C Parameter Symbol Conditions Ratings Unit Input voltage Vmax 25 V IN Allowable pin voltage V-SW 30 V IN V-PDR 6V IN REF 6V SS/HICCUP REF V FB REF V COMP REF V Allowable power dissipation Pd max Specified substrate *1 1.35 W Operating temperature Topr -40 to +85 C Storage temperature Tstg -55 to +150 C *1 Specified substrate : 50.0mm 50.0mm 1.6mm, fiberglass epoxy printed circuit board, 4 layers Note 1 : Absolute maximum ratings represent the values which cannot be exceeded for any length of time. Note 2 : Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. 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.
