| NTE7083 Integrated Circuit Vertical Deflection Circuit for Monitor Applications Description: The NTE7083 is an integrated circuit in a 13-Lead Staggered SIP type package designed for vertical deflection primarily in monitors and TV receivers. Features: D Fully Integrated, Few External Components D RC Oscillator with Wide Sync Range D Guard Circuit for Screen Protection D Synchronization by Positive or Negative Going Sync Pulse Absolute Maximum Ratings: Parameter Voltages Symbol V2 V11 V12 V13 Supply Voltages (VP) V10 V9 V7 V6 V5 V4 V3 Currents I1 I3 I4 I6, I7, I8 I9 I11 Note 1 -1.5 -0.1 +1.5 +3.0 A mA Test Conditions Min 0 0 0 0 0 0 0 0 0 0 -0.7 0 +3 0 Max 6 24 6 50 50 50 60 60 6 24 6 -1 -10 -5 Unit V V V V V V V V V V V mA mA mA D D D D Preamplifier Flyback Generator Internal Voltage Stabilizer Dual Frequency Criterion for Automatic Amplitude Switch-Over Note 1. I6, I7, and I8 are limited by SOAR protection circuit that ensures that a short-circuit between the output Pin7 and supply voltage or GND does not destroy the output stage. A short circuit may be soldered into the printed circuit board or may sometimes (non-periodically) occur in the applied circuit. Absolute Maximum Ratings (Cont'd): Parameter Storage Temperature Range Operating Ambient Temperature Range Maximum Junction Temperature Total Power Dissipation ESO Stability Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Mounting Base Symbol Tstg TA TJmax Ptot VESO RthJA RthJMB Note 2 Note 3 Note 2 Note 4 Test Conditions Min -25 -20 - - -2000 - - Max +150 +70 +150 - +2000 20 5 Unit C C C W V K/W K/W Note 2. The maximum value to the operating ambient temperature range and the power dissipation depends on the heatsink. Note 3. Internally liminted by thermal protection: switching temperature point at TJ = +150C 8C. Note 4. Human body model: 1.5k, 100pF, 5 pulses.
