Product Summary

The TDA4865AJ is a deflection booster for use in vertical deflection systems for frame frequencies up to 200 Hz. 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.

Parametrics

TDA4865AJ absolute maximum ratings: (1)VP1, supply voltage: 40 V max; (2)VP2, supply voltage: 70 V max; (3)VFB, flyback supply voltage of TDA4865J: 70 V; (4)VP3, flyback generator output voltage of TDA4865AJ: 0 to VP1 + 3 V; (5)Vi(INN), input voltage on pin INN: VP1 V max; (6)Vi(INP), input voltage on pin INP: VP1 V max; (7)Vo(VOUT), output voltage on pin VOUT: 72 V max; (8)IP2, supply current 2: ±2.0 A max; (9)Io(VOUT), output current on pin VOUT: ±2.0 A max; (10)IVFB, current during flyback of TDA4865J: ±2.0 A max; (11)IVP3 current during flyback of TDA4865AJ: ±2.0 A max; (12)Tstg, storage temperature: -25 to +150 ℃; (13)Tamb, ambient temperature: -20 to +75 ℃; (14)Tj, junction temperature: 150 ℃ max; (15)Vesd, electrostatic discharge voltage: machine model: -400 to +400 V; human body model: -4000 to +4000 V.
