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
