220V Monolithic Single Channel 37 MHz HDTV CRT
Driver
General DescriptionThe LM2432isa single channel high voltage CRT driver
circuit designedfor usein Rear-Projection and Direct-View
HDTV applications. TheIC containsa high input impedance,
wide band amplifier which canbe DC coupledtoa cathodea CRT. The amplifier hasits gain internallysetto −53 and
can drive CRT capacitive loadsas wellas resistive loads
presentin other applications, limited onlyby the package’s
power dissipation.
TheICis packagedina staggered 7-lead TO-220 molded
plastic power package designed specificallyto meet high
voltage spacing requirements. See the section “Power Dis-
sipation and Heatsink Calculation”for more information.
Features37 MHz bandwithat 110VPP output swing0Vto4V input range Greater than 130VPP output swing capabilityIK Current Output (Pin5)forIK feedback systems Stable with 0–20pF capacitive loads and inductive
peaking networks
Applications For Rear-Projection and Direct-View DC coupled CRT
applications usingupto 720p and 1080i HDTV formats Compatible with RGB video processors withIK feedback
for automatic cathode calibration
