| (R) STV8179F Vertical Deflection Booster for Slim CRTs DATASHEET OVERVIEW Power Amplifier Thermal Protection Output Current up to 3.6App Flyback Voltage up to 90V (on Pin 5) Suitable for DC Coupling Application External Flyback Supply HEPTAWATT (Plastic Package) Order Code: STV8179F DESCRIPTION Designed for monitors and high performance TVs, the STV8179F vertical deflection booster can handle flyback voltages of up to 90V. In addition, it is possible to have a flyback voltage which is more than double that of the supply (Pin 2). This allows decreasing power consumption or decreasing the flyback time for a given supply voltage. The STV8179F operates with supplies of up to 42V and outputs up to 3.6APP to drive the yoke. The STV8179F is offered in a HEPTAWATT package. 7 6 5 4 3 2 1 Input (Non Inverting) Output Stage Supply Output Ground Or Negative Supply Flyback Generator Supply Voltage Input (Inverting) Tab connected to pin 4 Output Supply Stage Voltage Supply 2 6 Flyback Supply 3 Inverting Input 1 Non-Inverting Input 7 - Power Amplifier + Thermal Protection 4 Ground or Negative Supply 5 Output STV8179F Rev. 3 January 2006 1/9 STV8179F Table of Contents Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Absolute Maximum Ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 Thermal Data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .4 Application Circuits . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .7 Package Mechanical Data 2/9 STV8179F Absolute Maximum Ratings 1 Absolute Maximum Ratings Symbol VS V6 V1,V7 IO I3 I3 VESD V3-V2 TOPER TSTG TJ Parameter Supply Voltage (Pin 2) (see note 1) Flyback Peak Voltage (Pin 6) (see note 1) Amplifier Input Voltage (Pins 1-7) (see note 1) Maximum Output Peak Current (see notes 2 and 3) Maximum Sink Current (t < 1ms) Maximum Source Current (t < 1ms) (in the diode, see Block Diagram) (see note 2) ESD Susceptibility: EIAJ Norm (200pF discharged through 0) Voltage Difference between Flyback Supply and Supply Voltage Operating Ambient Temperature Storage Temperature Junction Temperature Value 50 120 -0.3, + VS 3.0 3.0 3.0 300 50 -20, +75 -40, +150 + 150 Unit V V V A A A V V C C C Note: 1 Versus Pin 4. 2 The output current can reach 6A peak for t 10s (up to 120 Hz) 3 Provided SOAR is respected (see Figures 3 and 4). 2 Thermal Data Symbol Rth (j-c) TT TJR Parameter Junction-Case Thermal Resistance Max.
