SANYO 3LA78040B

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
