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
