TDA4865J; TDA4865AJ
Vertical de ection booster
Rev. 02 3 November 2006 Product data sheet
1. General description
The TDA4865J and TDA4865AJ are de ection boosters for use in vertical de ection systems for frame frequencies up to 200 Hz. The TDA4865J needs a separate yback supply voltage, so the supply voltages are independently adjustable to optimize power consumption and yback time. For the TDA4865AJ the yback supply voltage will be generated internally by doubling the supply voltage and therefore a separate yback supply voltage is not needed. Both circuits provide differential input stages.
2. Features
I I I I I Power ampli er with differential inputs Output current up to 3.8 A (p-p) High vertical de ection frequency up to 200 H- High linear sawtooth signal ampli cation Flyback generator: N TDA4865J: separate adjustable yback supply voltage up to 70 V N TDA4865AJ: internally doubled supply voltage (two supply voltages only for DC-coupled outputs)
