NTE7131
Integrated Circuit
DC–Coupled Vertical Deflection Circuit
Description:
The NTE7131 is an integrated circuit in a 9–Lead SIP type package designed for use in 90° and 110°
color deflection systems for field frequencies of 50 to 120Hz. The circuit provides a DC driven vertical
deflection output circuit, operating as a highly efficient class G system.
Features:
D Few External Components
D Highly Efficient Fully DC–Coupled Vertical Output Bridge Circuit
D Vertical Flyback Switch
D Guard Circuit
D Protection Against:
Short–Circuit of the Output Pins (7 and 4)
Short–Circuit of the Output Pins to VP
D Temperature (Thermal) Protection
D High EMC Immunity because of Common Mode Inputs
D A Guard Signal in Zoom Mode
Absolute Maximum Ratings:
