Ordering number : ENA0980A Monolithic Linear IC The Vertical Deflection Output IC With Bus Control Support for TVs and CRT Display LA78040B Overview 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 Symbol Conditions Ratings Unit Pump-up block supply voltage +B2 max 34 Output block supply voltage +B6 max 70 V Allowable power dissipation Pd max 9 W Deflection output current I5 max Mounted on an arbitrarily large heat sink.
