d0605 ms pc b8-4579 no.7966-1/4 http://onsemi.com semiconductor components industries, llc, 2013 july, 2013 LA78041 overview the LA78041 is a vertical deflection output ic for high image quality tv and crt displays that supports the use of a bus control system signal-processing ic. the sawtooth waveform from the bus control system signal-processing ic can directly drive the deflection yoke (including the dc component). color tv vertical deflection system adjustment functions can be controlled over a bus system by conn ecting the LA78041 to a our company la768x series or la769xx series bus control sy stem signal-processing ic. since the LA78041 provides a maximum deflection current of 2.2ap-p, it is optimal for large size crts. functions ? low power operation achieved by using integrated charge pump circuit. ? vertical output circuit. ? thermal protection circuit. ? excellent crossover characteristics. ? supports dc coupling. specifications maximum ratings at ta = 25 c parameter symbol conditions ratings unit pump-up block supply voltage +b2 max 34 v output block supply voltage +b6 max 70 v allowable power dissipation pd max mounted on an arbitrarily large heat sink. 9 w deflection output current i5 max -1.5 to +1.5 ap-o thermal resistance j-c 3 c /w operating temperature topr -20 to +85 c storage temperature tstg -40 to +150 c ordering number : en7966 monolithic linear ic tv and crt display vertical output ic with bus control support stresses exceeding maximum ratings may damage the device. maximum ratings are stress ratings only. functional operation above the recommended oper ating conditions is not implied. extended exposure to stresses above the recommended operating conditions may affect device reliabili ty.
