NXP Semiconductors TDA8351
The TDA8351 is a power circuit for use in 90° and 110° colour 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 protection
● High EMC immunity because of common mode inputs
● A guard signal in zoom mode.
