Vertical Deflection Output Circuit

w/Driver Circuit for TV Monitor

Description:

The NTE1855 is an integrated circuit in a 13–Lead SIP type package that contains the vertical deflec-

tion output circuit with a driver for small–aperture (maximum deflection current 1.8Ap–p) color/B & W

TV, monitor/display use. This device has such features as greatly reduced number of external parts

and low power dissipation. Since both DC feedback and AC feedback can be provided inside the IC,

it is easy to design the vertical deflection circuit.
