Integrated Circuit
DC−Coupled Vertical Deflection
and East−West Output Circuit
Description:
The NTE7162 is a power circuit in a 13−Lead Staggered SIP type package designed for use in 90°
and 110° color deflection systems for field frequencies of 50Hz to 120Hz. The circuit provides a DC
driven vertical deflection output circuit, operating as a highly effecient class G system and an East−
West driver for sinking the diode modulator current.

Note 1. A flyback supply voltage of > 50V up to 60V i allowed in application. A 220nF capacitor in
series with a 22Ω resistor (depending on I_O and the inductance of the coil) has to be con-
nected between Pin9 and GND. The decoupling capacitor of V_FB has to be connected be-
tween Pin8 and Pin4. The supply voltage line must have a resistance of 33Ω.
Note 2. I_O maximum determined by current protection.
Note 3. The operating area is limited by a straight line between the points V_O(sink) = 40V; I_O(sink) = 10µA
and V_O(sink) = 2V; I_O(sink) = 500mA.
