LM2433
220V Monolithic Single Channel 16 MHz EDTV CRT
Driver
General Description
The LM2433 is a single channel high voltage CRT driver
circuit designed for use in Rear-Projection and Direct-View
EDTV applications. The IC contains a high input impedance,
wide band amplifier which can be DC coupled to a cathode
of a CRT. The amplifier has its gain internally set to −53 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 a staggered 7-lead TO-220 molded
plastic power package designed specifically to meet high
voltage spacing requirements. See the section “Power Dis-
sipation and Heatsink Calculation” for more information.
Features
n 16 MHz bandwith at 110VPP output swing
n 0V to 4V input range
n Greater than 110VPP output swing capability
n IK Current Output (pin 5) for IK feedback systems
n Emitter (pin 6) access to increase voltage gain
Applications
n For Rear-Projection and Direct-View DC coupled CRT
applications using EDTV formats
n Compatible with RGB video processors with IK feedback
for automatic cathode calibration
