LM2423 220V Monolithic Triple Channel 15 MHz CRT DTV Driver July 2004 LM2423 220V Monolithic Triple Channel 15 MHz CRT DTV Driver General Description The LM2423 is a triple channel high voltage CRT driver circuit designed for use in DTV applications. The IC contains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to −54 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the package’s power dissipation. The IC is packaged in an industry standard 11-lead TO-220 molded plastic power package designed specifically to meet high voltage spacing requirements. See Thermal Considerations section. n Up to 170VPP output swing with AC coupling to cathodes n 0V to 5V input voltage range n Stable with 0 pF–20 pF capacitive loads and inductive peaking networks n Convenient TO-220 staggered thin lead package style Applications n AC coupled DTV applications using the 480p format as well as standard NTSC and PAL formats. Features n 15 MHz bandwidth at 130VPP output swing Connection Diagram Schematic Diagram 20114801 FIGURE 1.
