ILA8351

TECHNICAL DATA DC-COUPLED VERTICAL DEFLECTION CIRCUIT 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. GENERAL DESCRIPTION The ILA8351 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.
