TECHNICAL DATA
DC-coupled vertical deflection circuit
The KKA8356 is a power circuit for use in 90o and 110ocolour deflection systems for field frequencies
of 50 to 120 Hz. The circuit provides a DC driven vertical deflection output circuit, operating as a
highly efficient class G system.
FEATURES
Few external components
Highly efficient fully DC-coupled vertical output bridge circuit
Vertical flyback switch
Guard circuit
Protection against:
– short-circuit of the output pins (7 and 4)
– short-circuit of the output pins to VP
Temperature (thermal) protection
High EMC immunity because of common mode inputs
A guard signal in zoom mode
