ILA3654Q

ILA3654,ILA3654Q VERTICAL DEFLECTION AND GUARD CIRCUIT (110°) GENERAL DESCRIPTION The ILA3654 is a full performance vertical deflection output circuit for direct drive of the deflection coils and can be used for a wide range of 90° and 110° deflection systems. A guard circuit is provided which blanks the picture tube screen in the absence of deflection current. FEATURES · Direct drive to the deflection coils · 90° and 110° deflection system · Internal blanking guard circuit · Internal voltage stabilizer QUICK REFERENCE DATA Output voltage Output current (peak-to-peak) Supply voltage Guard circuit output voltage Operating ambient temperature range Storage temperature V5-2 I5(p-p) V9-2 V7-2 Tamb Tstg max. max. max. max. 60 V 3A 40 V 5,6 V -25 to +60 °C -55 to +150 °C THERMAL RESISTANCE From junction to mounting base Rth j-mb 3,5 to 4 K/W BLOCK DIAGRAM. .

Each output transistor can deliver 1,5 A maximum and the VCEO is 60 V. Protection of the output stage is such that the operation of the transistors remains well within the SOAR area in all circumstances at the output pin, (pin 5). This is obtained by the cooperation of the...
