NTE1855
Integrated Circuit
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.
Features:
D Low Power Dissipation due to On–Chip Pump–Up Circuit
D On–Chip 50/60Hz Vertical Size Control Circuit
D On–Chip Driver Circuit
D Vertical Output Circuit
D On–Chip Thermal Protection Circuit
D Minimum Number of External Parts Required
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
