| ICs for TV AN5769 H/V convergence correction IC s Overview The AN5769 is an IC to correct convergence in horizontal and vertical directions. It is possible to allow 100 mA (max.) DC current flow by connecting a coil between the output pins which operate with the reverse phase each other. 5.80.25 7.90.3 3.50.25 1.20.25 Unit: mm 0.45 -0.05 s Applications * CRT monitors 1.70.25 +0.1 * DC control input 0 V to 5 V * Output dynamic range 1.2 V to 3.8 V * Maximum output current 100 mA 2.54 s Features 12 11 10 9 8 7 6 5 4 3 2 1 3.3 0.50.1 1.20.25 28.00.3 1.70.25 HSIP012-P-0000 s Block Diagram 3 + 4 In-1 - 7 8 6 5 2 VCC1 = 12 V 1 Bias GND1 12 + In-2 - 10 11 9 GND2 GND3 29.40.3 1 AN5769 s Pin Descriptions Pin No. 1 2 Description Power supply 12 V (VCC1) Output block power supply 7 V (VCC2), protection resistor is required. 3 Output block power supply 7 V (VCC3), protection resistor is required. 4 5 H-conv. control input V-conv. control input Pin No. 6 7 8 9 10 11 12 Description Output block GND (GND3) H-conv. positive output H-conv. negative output Output block GND (GND2) V-conv. positive output V-conv. negative output GND (GND1) ICs for TV s Absolute Maximum Ratings Parameter Supply voltage Symbol VCC1 VCC2 VCC3 Supply current ICC1 ICC2 ICC3 Power dissipation *2 *1 Rating 13.5 11.05 11.05 28 150 150 1 171 -25 to +75 -55 to +150 Unit V mA PD Topr Tstg *1 mW C C Operating ambient temperature Storage temperature Note) 1. *1: Except for the operating ambient temperature and storage temperature, all ratings are for Ta = 25C. *2: The power dissipation shown is for the IC package at Ta = 75C. 2.
