Monolithic Linear IC
LA7875N, 7876N
Vertical Deflection Output Circuit
Overview
The LA7875N, LA7876N are designed for use in internet
TVs and high-resolution CRT monitors that require a
narrow vertical return period. These ICs succeed in
achieving a narrow vertical return period by adopting a
new 3× pump-up technique in the voltage pump-up circuit.
Since this allows the use of a reference voltage lower than
that used with the 2× pump-up technique, the LA7875N,
LA7876N achieve a significant reduction in power
dissipation. Also, since the bus control system signal-
processing IC can control these ICs and these ICs can
directly drive the deflection yoke for all frequencies down
to DC from the sawtooth wave output, shift operation,
which is required for wide aspect ratio television, can be
controlled from the bus. Since the LA7875N has a
maximum deflection output current of 2.2 A p-p, it is
appropriate for use in medium-size CRTs. Since the
LA7876N has a maximum deflection output current of 3 A
p-p, it is appropriate for use in larger CRTs.
