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

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test
conditions.
Note 3: All voltages are measured with respect to GND, unless otherwise specified.
Note 4: Linearity Error is the variation in DC gain from VIN = 1.15V to VIN = 4.35V.
Note 5: Input from signal generator: tr, tf < 2 ns. Slower inputs to the LM2433 will change the transient response and reduce power dissipation.
Note 6: IKERROR = IK – IOUT, where IK is the IK current output from pin 5 (IK) and IOUT is the cathode current into pin 2 (VOUT). IK can be measured with a precision
ammeter or calculated by measuring VIK across a known resistor value between pin 5 and GND. Refer to the “Cathode Current Output for IK Feedback Systems”
section for more information.
Note 7: Refer to the RGB Video Processor data sheet for IK leakage compensation, feedback operation, and adjustment range information.

AC Test Circuit
Note: 10pF load includes parasitic capacitance.
20146203
FIGURE 3. Test Circuit
Figure 3 shows a typical test circuit for evaluation of the LM2433. This circuit was designed to test the transient response of the
LM2433 in a 50environment without the use of an expensive FET probe. On the input side, a 50pulse generator output can
be AC coupled and biased with an external supply via the VADJ input. On the output side, the two 4990resistors form a 400:1
divider with the 50resistor and the oscilloscope. A test point can be included for easy use of an oscilloscope probe. A
compensation capacitor can be used to compensate the network to achieve a flat frequency response.
