LM2432
220V Monolithic Single Channel 37 MHz HDTV CRT
Driver
General Description
The LM2432 is a single channel high voltage CRT driver
circuit designed for use in Rear-Projection and Direct-View
HDTV 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
www.DataSphoeweetr4Udi.scsoipmation.
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 37 MHz bandwith at 110VPP output swing
n 0V to 4V input range
n Greater than 130VPP output swing capability
n IK Current Output (Pin 5) for IK feedback systems
n Stable with 0–20 pF capacitive loads and inductive
peaking networks
Applications
n For Rear-Projection and Direct-View DC coupled CRT
applications using up to 720p and 1080i HDTV formats
n Compatible with RGB video processors with IK feedback
for automatic cathode calibration
