Part Number : TDA4865AJ
Function : Vertical deflection booster
Package : SOT524-1, DIL 7 Leads
Manufacturers : NXP Semiconductors.
The TDA4865AJ 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.
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 I I I I Power ampliﬁer with differential inputs Output current up to 3.8 A (p-p) High vertical deﬂection frequency up to 200 Hz High linear sawtooth signal ampliﬁcation 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.
