2 / 15 page PIN CONNECTION (Top view) 2/15 Symbol Parameter Heptawatt Powerdip Rth j-case Thermal resistance junction-case max 4 °C/W - Rth j-pins Thermal resistance junction-pins max - 14 °C/W Rth j-amb Thermal resistance junction-ambient max 50 °C/W 80 °C/W* * Obtained with the GND pins soldered to printed circuit with minimized copper area. THERMAL DATA HEPTAWATT POWERDIP NAME FUNCTION 1 7 SUPPLY VOLTAGE Unregulated voltage input. An internal regulator powers the internal logic. 2 10 FEEDBACK INPUT The feedback terminal of the regulation loop. The output is connected directly to this terminal for 5.1V operation; it is connected via a divider for higher voltages. 3 11 FREQUENCY COMPENSATION A series RC network connected between this terminal and ground determines the regulation loop gain characteristics. PIN FUNCTIONS Symbol Parameter Value Unit V7 Input voltage 50 V V7 -V2 Input to output voltage difference 50 V V2 Negative output DC voltage -1 V Output peak voltage at t = 0.1 µs; f = 100KHz -5 V V11,V15 Voltage at pin 11, 15 5.5 V V10 Voltage at pin 10 7 V I11 Pin 11 sink current 1 mA I14 Pin 14 source current 20 mA Ptot Power dissipation at Tpins ≤ 90°C (Powerdip) Tcase ≤ 90°C (Heptawatt) 4.3 15 W W Tj,Tstg Junction and storage temperature -40 to 150 °C ABSOLUTE MAXIMUM RATINGS L4962 |
