Vertical Output ICs Vertical Output IC
The LA7847 and LA7848 are EW drive and vertical deflection output ICs for high-definition TV and CRT displays in systems that
use a bus control system signal-processing IC. These ICs can directly drive (including DC component) the deflection yoke from the
sawtooth wave output from the bus control system signal-processing IC. Similarly, the diode modulator block can be driven from the
parabolic wave output.
The color TV vertical deflection system and EW adjustment functions can be controlled from the bus system when either of these ICs
is used in conjunction with a Sanyo LA768X or LA769XX series TV bus control system signal-processing IC. The LA7847 provides
a maximum output block voltage of 72 V, a maximum deflection current of 2.2 A p-p, and an EW drive current of 0.4 A, and thus is
optimal for large diameter CRTs. The LA7848 provides a maximum output block voltage of 92 V, a maximum deflection current of
2.2 A p-p, and an EW drive current of 0.4 A, and thus is optimal for large diameter CRTs.
Built-in charge pump circuit for low power operation
