TDA4865J - Vertical Deflection Booster

Description

The TDA4865J and TDA4865AJ are deflection boosters for use in vertical deflection systems for frame frequencies up to 200 Hz.

The TDA4865J needs a separate flyback supply voltage, so the supply voltages are independently adjustable to optimize power consumption and flyback time.

Features

  • I Power amplifier with differential inputs I Output current up to 3.8 A (p-p) I High vertical deflection frequency up to 200 Hz I High linear sawtooth signal amplification I Flyback generator: N TDA4865J: separate adjustable flyback supply voltage up to 70 V N TDA4865AJ: internally doubled supply voltage (two supply voltages only for DC-coupled outputs) 3.

TDA4865J; TDA4865AJ Vertical deflection booster Rev. 02 — 3 November 2006 Product data sheet 1. General description The TDA4865J and TDA4865AJ are deflection boosters for use in vertical deflection systems for frame frequencies up to 200 Hz. The TDA4865J needs a separate flyback supply voltage, so the supply voltages are independently adjustable to optimize power consumption and flyback time. For the TDA4865AJ the flyback supply voltage will be generated internally by doubling the supply voltage and therefore a separate flyback supply voltage is not needed. Both circuits provide differential input stages. 2. Features I Power amplifier with differential inputs I Output current up to 3.
