Ordering number : ENA0980 Monolithic Linear IC LA78040B Overview The Vertical Deflection Output IC With Bus Control Support for TVs and CRT Display The LA78040B is a vertical deflection output IC for TVs and CRT displays with excellent image quality that use a BUS control system signal processing IC. This IC can drive the direct (even including a DC component) deflection yoke with the saw tooth wave output from the BUS control system signal processing IC. Functions • Low power dissipation due to built-in pump-up circuit • Vertical output circuit • Thermal protection circuit built in • Excellent crossover characteristics • DC coupling possible Specifications Maximum Ratings at Ta = 25°C Parameter Pump-up block supply voltage Output block supply voltage Allowable power dissipation Deflection output current Thermal resistance Operating temperature Storage temperature Symbol VCC2 max VCC6 max Pd max I5 max θj-c Topr Tstg Mounted on an arbitrarily large heat sink.
