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.
