| ICs for TV AN5768 TILT correction IC s Overview The AN5768 is a rotation correction (TILT) IC for CRT monitor incorporating a driving transistor. It enables 250 mA (max.) DC current flow by connecting a coil between the output pins which operate with a reverse phase each other. 19.90.1 18.30.25 2.650.1 8.40.25 6.30.3 7.10.25 5.80.25 1.50.25 9 8 7 6 5 4 3 2 1 5.60.25 3.750.25 Unit: mm 3.30.1 0.50.1 1.20.25 15.0 1.70.25 s Applications 1.7 0.25 * CRT monitors HSIP009-P-0000 s Block Diagram 2V CC2 + 4 In - 7 8 VCC1 1 12 V Bias 5 GND2 9 3 GND1 6 +0.1 0.45 -0.05 * DC control input: 0 V to 5 V * Output dynamic range: 1.2 V to 3.8 V * Maximum output current: 250 mA 0.10.05 2.54 s Features 22.30.3 1 AN5768 s Pin Descriptions Pin No. 1 2 3 4 5 6 7 8 9 Description Supply voltage 12 V (VCC1) Output block supply voltage 7 V (VCC2), Protective resistor is needed.
