Ordering number : ENA1902A LV5681P Monolithic Linear IC Multi-Power Supply System IC LV5681P Specifications Absolute Maximum Ratings at Ta = 25C Parameter Conditions Conditions Ratings Unit Supply voltage V max 36 V CC Peak supply voltage V peak See below for the waveform applied. 50 V CC Allowable Power dissipation Pd max Independent IC Ta 25C 1.5 W Al heat sink * 5.6 W With an infinity heat sink 32.5 W Junction temperature Tj max 150 C Operating ambient temperature Topr -40 to +85 C Storage temperature Tstg -55 to +150 C * : When the Aluminum heat sink (50mm 50mm 1.5mm) is used 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. Allowable Operating range at Ta = 25C Parameter Conditions Ratings Unit Operating supply voltage 1 V output, SW output, ACC output 7.5 to 16 V DD Operating supply voltage 2 ILM output at 10V 12 to 16 V ILM output at 8V 10 to 16 V Operating supply voltage 3 Audio output at 9V 10 to 16 V Operating supply voltage 4 CD output (CD output current = 1.3A) 10.5 to 16 V CD output (CD output current 1A) 10 to 16 V Electrical Characteristics at Ta = 25C, V = 14.4V CC *: All the specifications are defined based on the tests that Tj is almost equal to Ta (=25C). To suppress the rise of Tj in the junction temperature as much as possible, it tests by the pulse loading.
